Given numbers are 123, 870, 645, 926
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 870) = 35670
GCD(123, 870) = ( 123 x 870 ) / 35670
= 123 / 870
= 123
Step2:
LCM(3, 645) = 645
GCD(3, 645) = ( 3 x 645 ) / 645
= 3 / 645
= 3
Step3:
LCM(3, 926) = 2778
GCD(3, 926) = ( 3 x 926 ) / 2778
= 3 / 926
= 3
So, Greatest Common Divisor of 123, 870, 645, 926 is 1
