GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 873) = 163251
GCD(561, 873) = ( 561 x 873 ) / 163251
= 561 / 873
= 561
Step2:
LCM(3, 413) = 1239
GCD(3, 413) = ( 3 x 413 ) / 1239
= 3 / 413
= 3
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 561, 873, 413, 915 is 1
