Given numbers are 909, 636, 578, 851

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

Apply this formula for all numbers.

Step1:

LCM(909, 636) = 192708

GCD(909, 636) = ( 909 x 636 ) / 192708

= 909 / 636

= 909

Step2:

LCM(3, 578) = 1734

GCD(3, 578) = ( 3 x 578 ) / 1734

= 3 / 578

= 3

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 909, 636, 578, 851 is 1
