Steps to Calculate GCD of 138, 287, 658, 298 using LCM Formula

Given numbers are 138, 287, 658, 298

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

Apply this formula for all numbers.

Step1:

LCM(138, 287) = 39606

GCD(138, 287) = ( 138 x 287 ) / 39606

= 138 / 287

= 138


Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1


Step3:

LCM(1, 298) = 298

GCD(1, 298) = ( 1 x 298 ) / 298

= 1 / 298

= 1


So, Greatest Common Divisor of 138, 287, 658, 298 is 1
