Given numbers are 123, 813, 221, 607
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 813) = 33333
GCD(123, 813) = ( 123 x 813 ) / 33333
= 123 / 813
= 123
Step2:
LCM(3, 221) = 663
GCD(3, 221) = ( 3 x 221 ) / 663
= 3 / 221
= 3
Step3:
LCM(1, 607) = 607
GCD(1, 607) = ( 1 x 607 ) / 607
= 1 / 607
= 1
So, Greatest Common Divisor of 123, 813, 221, 607 is 1
