Given numbers are 644, 298, 931, 910

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

Apply this formula for all numbers.

Step1:

LCM(644, 298) = 95956

GCD(644, 298) = ( 644 x 298 ) / 95956

= 644 / 298

= 644

Step2:

LCM(2, 931) = 1862

GCD(2, 931) = ( 2 x 931 ) / 1862

= 2 / 931

= 2

Step3:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

So, Greatest Common Divisor of 644, 298, 931, 910 is 1
