Steps to Calculate GCD of 97, 42, 49, 70 using LCM Formula
Given numbers are 97, 42, 49, 70
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(97, 42) = 4074
GCD(97, 42) = ( 97 x 42 ) / 4074
= 97 / 42
= 97
Step2:
LCM(1, 49) = 49
GCD(1, 49) = ( 1 x 49 ) / 49
= 1 / 49
= 1
Step3:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
So, Greatest Common Divisor of 97, 42, 49, 70 is 1
