Given numbers are 640, 990, 430, 953

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

Apply this formula for all numbers.

Step1:

LCM(640, 990) = 63360

GCD(640, 990) = ( 640 x 990 ) / 63360

= 640 / 990

= 640

Step2:

LCM(10, 430) = 430

GCD(10, 430) = ( 10 x 430 ) / 430

= 10 / 430

= 10

Step3:

LCM(10, 953) = 9530

GCD(10, 953) = ( 10 x 953 ) / 9530

= 10 / 953

= 10

So, Greatest Common Divisor of 640, 990, 430, 953 is 1
