Given numbers are 561, 852, 623, 477
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 852) = 159324
GCD(561, 852) = ( 561 x 852 ) / 159324
= 561 / 852
= 561
Step2:
LCM(3, 623) = 1869
GCD(3, 623) = ( 3 x 623 ) / 1869
= 3 / 623
= 3
Step3:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
So, Greatest Common Divisor of 561, 852, 623, 477 is 1
