Given numbers are 561, 646, 503, 914
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 646) = 21318
GCD(561, 646) = ( 561 x 646 ) / 21318
= 561 / 646
= 561
Step2:
LCM(17, 503) = 8551
GCD(17, 503) = ( 17 x 503 ) / 8551
= 17 / 503
= 17
Step3:
LCM(1, 914) = 914
GCD(1, 914) = ( 1 x 914 ) / 914
= 1 / 914
= 1
So, Greatest Common Divisor of 561, 646, 503, 914 is 1
