Steps to Calculate GCD of 257, 391, 125, 268 using LCM Formula

Given numbers are 257, 391, 125, 268

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

Apply this formula for all numbers.

Step1:

LCM(257, 391) = 100487

GCD(257, 391) = ( 257 x 391 ) / 100487

= 257 / 391

= 257


Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1


Step3:

LCM(1, 268) = 268

GCD(1, 268) = ( 1 x 268 ) / 268

= 1 / 268

= 1


So, Greatest Common Divisor of 257, 391, 125, 268 is 1
