Given numbers are 646, 444, 977, 906

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

Apply this formula for all numbers.

Step1:

LCM(646, 444) = 143412

GCD(646, 444) = ( 646 x 444 ) / 143412

= 646 / 444

= 646

Step2:

LCM(2, 977) = 1954

GCD(2, 977) = ( 2 x 977 ) / 1954

= 2 / 977

= 2

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 646, 444, 977, 906 is 1
