Given numbers are 968, 642, 869, 771

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

Apply this formula for all numbers.

Step1:

LCM(968, 642) = 310728

GCD(968, 642) = ( 968 x 642 ) / 310728

= 968 / 642

= 968

Step2:

LCM(2, 869) = 1738

GCD(2, 869) = ( 2 x 869 ) / 1738

= 2 / 869

= 2

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 968, 642, 869, 771 is 1
