Question

find HCF of 378 180 and 420 by prime factorization method. is HCF multiplied LCM of three number equal to the product of the three number is HCF multiplied LCM of three number equal to the product of the three number? prove?????​

Answer 1

Answer:hope it helps, if so then please mark it as brainliest, thanks in advance.....:-)

Step-by-step explanation:

Prime factors of 378 = 2 × 3 × 3 × 3 × 7

Prime factors of 180 = 2 × 2 × 3 × 3 × 5

Prime factors of 420 = 2 × 2 × 3 × 5 × 7

So, HCF of 378, 180 and 420 is 2 × 3 = 6

And LCM of 378, 180 and 420 is 2 × 2 × 3 × 3 × 3 × 5 × 7 = 3780

So, let us check whether LCM (378, 180 and 420) × HCF (378, 180 and 420) is equal to the product of the three numbers

3780 × 6 = 378 × 180 × 420

22680 ≠ 28576800

Hence LCM*HCF is not equal to the product of the three numbers.
