Given numbers are 640, 844, 878, 711

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

Apply this formula for all numbers.

Step1:

LCM(640, 844) = 135040

GCD(640, 844) = ( 640 x 844 ) / 135040

= 640 / 844

= 640

Step2:

LCM(4, 878) = 1756

GCD(4, 878) = ( 4 x 878 ) / 1756

= 4 / 878

= 4

Step3:

LCM(2, 711) = 1422

GCD(2, 711) = ( 2 x 711 ) / 1422

= 2 / 711

= 2

So, Greatest Common Divisor of 640, 844, 878, 711 is 1
