Given numbers are 561, 579, 354, 617
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 579) = 108273
GCD(561, 579) = ( 561 x 579 ) / 108273
= 561 / 579
= 561
Step2:
LCM(3, 354) = 354
GCD(3, 354) = ( 3 x 354 ) / 354
= 3 / 354
= 3
Step3:
LCM(3, 617) = 1851
GCD(3, 617) = ( 3 x 617 ) / 1851
= 3 / 617
= 3
So, Greatest Common Divisor of 561, 579, 354, 617 is 1
