Given numbers are 402, 968, 39, 131

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

Apply this formula for all numbers.

Step1:

LCM(402, 968) = 194568

GCD(402, 968) = ( 402 x 968 ) / 194568

= 402 / 968

= 402

Step2:

LCM(2, 39) = 78

GCD(2, 39) = ( 2 x 39 ) / 78

= 2 / 39

= 2

Step3:

LCM(1, 131) = 131

GCD(1, 131) = ( 1 x 131 ) / 131

= 1 / 131

= 1

So, Greatest Common Divisor of 402, 968, 39, 131 is 1
