Given numbers are 868, 972, 724, 909

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

Apply this formula for all numbers.

Step1:

LCM(868, 972) = 210924

GCD(868, 972) = ( 868 x 972 ) / 210924

= 868 / 972

= 868

Step2:

LCM(4, 724) = 724

GCD(4, 724) = ( 4 x 724 ) / 724

= 4 / 724

= 4

Step3:

LCM(4, 909) = 3636

GCD(4, 909) = ( 4 x 909 ) / 3636

= 4 / 909

= 4

So, Greatest Common Divisor of 868, 972, 724, 909 is 1
