Given numbers are 671, 858, 641, 252
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 858) = 52338
GCD(671, 858) = ( 671 x 858 ) / 52338
= 671 / 858
= 671
Step2:
LCM(11, 641) = 7051
GCD(11, 641) = ( 11 x 641 ) / 7051
= 11 / 641
= 11
Step3:
LCM(1, 252) = 252
GCD(1, 252) = ( 1 x 252 ) / 252
= 1 / 252
= 1
So, Greatest Common Divisor of 671, 858, 641, 252 is 1
