Steps to Calculate GCD of 721, 261, 63, 537 using LCM Formula
Given numbers are 721, 261, 63, 537
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 261) = 188181
GCD(721, 261) = ( 721 x 261 ) / 188181
= 721 / 261
= 721
Step2:
LCM(1, 63) = 63
GCD(1, 63) = ( 1 x 63 ) / 63
= 1 / 63
= 1
Step3:
LCM(1, 537) = 537
GCD(1, 537) = ( 1 x 537 ) / 537
= 1 / 537
= 1
So, Greatest Common Divisor of 721, 261, 63, 537 is 1
