Given numbers are 561, 102, 305, 976
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 102) = 1122
GCD(561, 102) = ( 561 x 102 ) / 1122
= 561 / 102
= 561
Step2:
LCM(51, 305) = 15555
GCD(51, 305) = ( 51 x 305 ) / 15555
= 51 / 305
= 51
Step3:
LCM(1, 976) = 976
GCD(1, 976) = ( 1 x 976 ) / 976
= 1 / 976
= 1
So, Greatest Common Divisor of 561, 102, 305, 976 is 1
