Steps to Calculate GCD of 531, 621, 55, 513 using LCM Formula
Given numbers are 531, 621, 55, 513
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(531, 621) = 36639
GCD(531, 621) = ( 531 x 621 ) / 36639
= 531 / 621
= 531
Step2:
LCM(9, 55) = 495
GCD(9, 55) = ( 9 x 55 ) / 495
= 9 / 55
= 9
Step3:
LCM(1, 513) = 513
GCD(1, 513) = ( 1 x 513 ) / 513
= 1 / 513
= 1
So, Greatest Common Divisor of 531, 621, 55, 513 is 1
