Given numbers are 640, 403, 895, 772

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

Apply this formula for all numbers.

Step1:

LCM(640, 403) = 257920

GCD(640, 403) = ( 640 x 403 ) / 257920

= 640 / 403

= 640

Step2:

LCM(1, 895) = 895

GCD(1, 895) = ( 1 x 895 ) / 895

= 1 / 895

= 1

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 640, 403, 895, 772 is 1
