Given numbers are 642, 717, 859, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 717) = 153438
GCD(642, 717) = ( 642 x 717 ) / 153438
= 642 / 717
= 642
Step2:
LCM(3, 859) = 2577
GCD(3, 859) = ( 3 x 859 ) / 2577
= 3 / 859
= 3
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 642, 717, 859, 571 is 1
