Steps to Calculate GCD of 974, 414, 87, 391 using LCM Formula
Given numbers are 974, 414, 87, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(974, 414) = 201618
GCD(974, 414) = ( 974 x 414 ) / 201618
= 974 / 414
= 974
Step2:
LCM(2, 87) = 174
GCD(2, 87) = ( 2 x 87 ) / 174
= 2 / 87
= 2
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 974, 414, 87, 391 is 1
