GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 475) = 266475
GCD(561, 475) = ( 561 x 475 ) / 266475
= 561 / 475
= 561
Step2:
LCM(1, 248) = 248
GCD(1, 248) = ( 1 x 248 ) / 248
= 1 / 248
= 1
Step3:
LCM(1, 480) = 480
GCD(1, 480) = ( 1 x 480 ) / 480
= 1 / 480
= 1
So, Greatest Common Divisor of 561, 475, 248, 480 is 1
