Steps to Calculate GCD of 487, 755, 257, 129 using LCM Formula
Given numbers are 487, 755, 257, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 755) = 367685
GCD(487, 755) = ( 487 x 755 ) / 367685
= 487 / 755
= 487
Step2:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 487, 755, 257, 129 is 1
