Given numbers are 457, 513, 138, 868

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

Apply this formula for all numbers.

Step1:

LCM(457, 513) = 234441

GCD(457, 513) = ( 457 x 513 ) / 234441

= 457 / 513

= 457

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 868) = 868

GCD(1, 868) = ( 1 x 868 ) / 868

= 1 / 868

= 1

So, Greatest Common Divisor of 457, 513, 138, 868 is 1
