Steps to Calculate GCD of 178, 639, 216, 637 using LCM Formula

Given numbers are 178, 639, 216, 637

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(178, 639) = 113742

GCD(178, 639) = ( 178 x 639 ) / 113742

= 178 / 639

= 178


Step2:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1


Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1


So, Greatest Common Divisor of 178, 639, 216, 637 is 1
