Steps to Calculate GCD of 217, 961, 755, 173 using LCM Formula
Given numbers are 217, 961, 755, 173
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 961) = 6727
GCD(217, 961) = ( 217 x 961 ) / 6727
= 217 / 961
= 217
Step2:
LCM(31, 755) = 23405
GCD(31, 755) = ( 31 x 755 ) / 23405
= 31 / 755
= 31
Step3:
LCM(1, 173) = 173
GCD(1, 173) = ( 1 x 173 ) / 173
= 1 / 173
= 1
So, Greatest Common Divisor of 217, 961, 755, 173 is 1
