Given numbers are 856, 640, 440, 619

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

Apply this formula for all numbers.

Step1:

LCM(856, 640) = 68480

GCD(856, 640) = ( 856 x 640 ) / 68480

= 856 / 640

= 856

Step2:

LCM(8, 440) = 440

GCD(8, 440) = ( 8 x 440 ) / 440

= 8 / 440

= 8

Step3:

LCM(8, 619) = 4952

GCD(8, 619) = ( 8 x 619 ) / 4952

= 8 / 619

= 8

So, Greatest Common Divisor of 856, 640, 440, 619 is 1
