Given numbers are 961, 973, 100, 647

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

Apply this formula for all numbers.

Step1:

LCM(961, 973) = 935053

GCD(961, 973) = ( 961 x 973 ) / 935053

= 961 / 973

= 961

Step2:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 961, 973, 100, 647 is 1
