HCF (Highest Common Factor) - Definition, How to Find HCF, Examples …
WebMay 10, 2015 · The Highest Common Factor of the two numbers is 6 The Lowest Common Multiple is a multiple of 15. Write a pair of numbers that Martin could be thinking of. It took me an embarrassingly long time to come up with a solution but I still don't have a method that will work quickly for different numbers. WebThe greatest common factor (gcf), or highest common factor (hcf), of two or more integers (at least one of which is not zero), is the largest positive integer that divides the numbers without a remainder. It is the highest number that divides exactly into two or more numbers. It is the "greatest" thing for simplifying fractions. flathead electric pay by phone
Find the HCF of 180, 240 and 360 by long division method.
WebExample 1: Find the HCF of 144 and 180, if their LCM is 720. Solution: ∵ LCM × HCF = 144 × 180 ⇒ HCF (144, 180) = (144 × 180)/720 = 36 Therefore, the highest common factor of 144 and 180 is 36. Example … WebHighest Common Factor of 90,180 is 90. Step 1: Since 180 > 90, we apply the division lemma to 180 and 90, to get. 180 = 90 x 2 + 0. The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 90, the HCF of 90 and 180 is 90. Notice that 90 = HCF (180,90) . Webof numbers. Example. Find the HCF and LCM of 24 and 180. Break the numbers into the product of prime factors using prime factor trees, as before.
