Steps to Calculate GCD of 221, 494, 530, 187 using LCM Formula
Given numbers are 221, 494, 530, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(221, 494) = 8398
GCD(221, 494) = ( 221 x 494 ) / 8398
= 221 / 494
= 221
Step2:
LCM(13, 530) = 6890
GCD(13, 530) = ( 13 x 530 ) / 6890
= 13 / 530
= 13
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 221, 494, 530, 187 is 1
