Given numbers are 515, 968, 931, 142

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

Apply this formula for all numbers.

Step1:

LCM(515, 968) = 498520

GCD(515, 968) = ( 515 x 968 ) / 498520

= 515 / 968

= 515

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

So, Greatest Common Divisor of 515, 968, 931, 142 is 1
