Given numbers are 561, 411, 562, 521
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 411) = 76857
GCD(561, 411) = ( 561 x 411 ) / 76857
= 561 / 411
= 561
Step2:
LCM(3, 562) = 1686
GCD(3, 562) = ( 3 x 562 ) / 1686
= 3 / 562
= 3
Step3:
LCM(1, 521) = 521
GCD(1, 521) = ( 1 x 521 ) / 521
= 1 / 521
= 1
So, Greatest Common Divisor of 561, 411, 562, 521 is 1
