The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 561, 470, 102, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 470) = 263670
GCD(561, 470) = ( 561 x 470 ) / 263670
= 561 / 470
= 561
Step2:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 561, 470, 102, 311 is 1
