Given numbers are 640, 788, 869, 998

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

Apply this formula for all numbers.

Step1:

LCM(640, 788) = 126080

GCD(640, 788) = ( 640 x 788 ) / 126080

= 640 / 788

= 640

Step2:

LCM(4, 869) = 3476

GCD(4, 869) = ( 4 x 869 ) / 3476

= 4 / 869

= 4

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 640, 788, 869, 998 is 1
