Steps to Calculate GCD of 277, 513, 453, 645 using LCM Formula
Given numbers are 277, 513, 453, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(277, 513) = 142101
GCD(277, 513) = ( 277 x 513 ) / 142101
= 277 / 513
= 277
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 277, 513, 453, 645 is 1
