Given numbers are 561, 242, 859, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 242) = 12342
GCD(561, 242) = ( 561 x 242 ) / 12342
= 561 / 242
= 561
Step2:
LCM(11, 859) = 9449
GCD(11, 859) = ( 11 x 859 ) / 9449
= 11 / 859
= 11
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 561, 242, 859, 287 is 1
