Given numbers are 321, 613, 544, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 613) = 196773
GCD(321, 613) = ( 321 x 613 ) / 196773
= 321 / 613
= 321
Step2:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 321, 613, 544, 561 is 1
