Given numbers are 968, 253, 782, 646

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

Apply this formula for all numbers.

Step1:

LCM(968, 253) = 22264

GCD(968, 253) = ( 968 x 253 ) / 22264

= 968 / 253

= 968

Step2:

LCM(11, 782) = 8602

GCD(11, 782) = ( 11 x 782 ) / 8602

= 11 / 782

= 11

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 968, 253, 782, 646 is 1
