Given numbers are 821, 117, 572, 718

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

Apply this formula for all numbers.

Step1:

LCM(821, 117) = 96057

GCD(821, 117) = ( 821 x 117 ) / 96057

= 821 / 117

= 821

Step2:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

Step3:

LCM(1, 718) = 718

GCD(1, 718) = ( 1 x 718 ) / 718

= 1 / 718

= 1

So, Greatest Common Divisor of 821, 117, 572, 718 is 1
