Given numbers are 571, 821, 170, 972

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

Apply this formula for all numbers.

Step1:

LCM(571, 821) = 468791

GCD(571, 821) = ( 571 x 821 ) / 468791

= 571 / 821

= 571

Step2:

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

= 1 / 170

= 1

Step3:

LCM(1, 972) = 972

GCD(1, 972) = ( 1 x 972 ) / 972

= 1 / 972

= 1

So, Greatest Common Divisor of 571, 821, 170, 972 is 1
