Given numbers are 851, 640, 571, 105

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

Apply this formula for all numbers.

Step1:

LCM(851, 640) = 544640

GCD(851, 640) = ( 851 x 640 ) / 544640

= 851 / 640

= 851

Step2:

LCM(1, 571) = 571

GCD(1, 571) = ( 1 x 571 ) / 571

= 1 / 571

= 1

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 851, 640, 571, 105 is 1
