Given numbers are 891, 645, 550, 539
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 645) = 191565
GCD(891, 645) = ( 891 x 645 ) / 191565
= 891 / 645
= 891
Step2:
LCM(3, 550) = 1650
GCD(3, 550) = ( 3 x 550 ) / 1650
= 3 / 550
= 3
Step3:
LCM(1, 539) = 539
GCD(1, 539) = ( 1 x 539 ) / 539
= 1 / 539
= 1
So, Greatest Common Divisor of 891, 645, 550, 539 is 1
