Given numbers are 561, 504, 821, 725
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 504) = 94248
GCD(561, 504) = ( 561 x 504 ) / 94248
= 561 / 504
= 561
Step2:
LCM(3, 821) = 2463
GCD(3, 821) = ( 3 x 821 ) / 2463
= 3 / 821
= 3
Step3:
LCM(1, 725) = 725
GCD(1, 725) = ( 1 x 725 ) / 725
= 1 / 725
= 1
So, Greatest Common Divisor of 561, 504, 821, 725 is 1
