Given numbers are 561, 789, 670, 310
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 789) = 147543
GCD(561, 789) = ( 561 x 789 ) / 147543
= 561 / 789
= 561
Step2:
LCM(3, 670) = 2010
GCD(3, 670) = ( 3 x 670 ) / 2010
= 3 / 670
= 3
Step3:
LCM(1, 310) = 310
GCD(1, 310) = ( 1 x 310 ) / 310
= 1 / 310
= 1
So, Greatest Common Divisor of 561, 789, 670, 310 is 1
