Given numbers are 570, 166, 557, 648
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(570, 166) = 47310
GCD(570, 166) = ( 570 x 166 ) / 47310
= 570 / 166
= 570
Step2:
LCM(2, 557) = 1114
GCD(2, 557) = ( 2 x 557 ) / 1114
= 2 / 557
= 2
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 570, 166, 557, 648 is 1
