Steps to Calculate GCD of 497, 138, 83, 430 using LCM Formula
Given numbers are 497, 138, 83, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(497, 138) = 68586
GCD(497, 138) = ( 497 x 138 ) / 68586
= 497 / 138
= 497
Step2:
LCM(1, 83) = 83
GCD(1, 83) = ( 1 x 83 ) / 83
= 1 / 83
= 1
Step3:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
So, Greatest Common Divisor of 497, 138, 83, 430 is 1
