Given numbers are 123, 643, 330, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 643) = 79089
GCD(123, 643) = ( 123 x 643 ) / 79089
= 123 / 643
= 123
Step2:
LCM(1, 330) = 330
GCD(1, 330) = ( 1 x 330 ) / 330
= 1 / 330
= 1
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 123, 643, 330, 356 is 1
