Given numbers are 620, 442, 64, 953

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

Apply this formula for all numbers.

Step1:

LCM(620, 442) = 137020

GCD(620, 442) = ( 620 x 442 ) / 137020

= 620 / 442

= 620

Step2:

LCM(2, 64) = 64

GCD(2, 64) = ( 2 x 64 ) / 64

= 2 / 64

= 2

Step3:

LCM(2, 953) = 1906

GCD(2, 953) = ( 2 x 953 ) / 1906

= 2 / 953

= 2

So, Greatest Common Divisor of 620, 442, 64, 953 is 1
