Steps to Calculate GCD of 257, 661, 946, 109 using LCM Formula
Given numbers are 257, 661, 946, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 661) = 169877
GCD(257, 661) = ( 257 x 661 ) / 169877
= 257 / 661
= 257
Step2:
LCM(1, 946) = 946
GCD(1, 946) = ( 1 x 946 ) / 946
= 1 / 946
= 1
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 257, 661, 946, 109 is 1
