Steps to Calculate GCD of 370, 497, 31, 638 using LCM Formula
Given numbers are 370, 497, 31, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(370, 497) = 183890
GCD(370, 497) = ( 370 x 497 ) / 183890
= 370 / 497
= 370
Step2:
LCM(1, 31) = 31
GCD(1, 31) = ( 1 x 31 ) / 31
= 1 / 31
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 370, 497, 31, 638 is 1
