Given numbers are 646, 957, 719, 828

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

Apply this formula for all numbers.

Step1:

LCM(646, 957) = 618222

GCD(646, 957) = ( 646 x 957 ) / 618222

= 646 / 957

= 646

Step2:

LCM(1, 719) = 719

GCD(1, 719) = ( 1 x 719 ) / 719

= 1 / 719

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 646, 957, 719, 828 is 1
