Given numbers are 545, 981, 643, 110
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(545, 981) = 4905
GCD(545, 981) = ( 545 x 981 ) / 4905
= 545 / 981
= 545
Step2:
LCM(109, 643) = 70087
GCD(109, 643) = ( 109 x 643 ) / 70087
= 109 / 643
= 109
Step3:
LCM(1, 110) = 110
GCD(1, 110) = ( 1 x 110 ) / 110
= 1 / 110
= 1
So, Greatest Common Divisor of 545, 981, 643, 110 is 1
