Steps to Calculate GCD of 797, 498, 15, 155 using LCM Formula
Given numbers are 797, 498, 15, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(797, 498) = 396906
GCD(797, 498) = ( 797 x 498 ) / 396906
= 797 / 498
= 797
Step2:
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
= 1 / 15
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 797, 498, 15, 155 is 1
