Given numbers are 105, 372, 617, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 372) = 13020
GCD(105, 372) = ( 105 x 372 ) / 13020
= 105 / 372
= 105
Step2:
LCM(3, 617) = 1851
GCD(3, 617) = ( 3 x 617 ) / 1851
= 3 / 617
= 3
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 105, 372, 617, 861 is 1
