Given numbers are 975, 399, 649, 651

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

Apply this formula for all numbers.

Step1:

LCM(975, 399) = 129675

GCD(975, 399) = ( 975 x 399 ) / 129675

= 975 / 399

= 975

Step2:

LCM(3, 649) = 1947

GCD(3, 649) = ( 3 x 649 ) / 1947

= 3 / 649

= 3

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 975, 399, 649, 651 is 1
