GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 858) = 14586
GCD(561, 858) = ( 561 x 858 ) / 14586
= 561 / 858
= 561
Step2:
LCM(33, 480) = 5280
GCD(33, 480) = ( 33 x 480 ) / 5280
= 33 / 480
= 33
Step3:
LCM(3, 718) = 2154
GCD(3, 718) = ( 3 x 718 ) / 2154
= 3 / 718
= 3
So, Greatest Common Divisor of 561, 858, 480, 718 is 1
