Given numbers are 129, 870, 456, 185
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 870) = 37410
GCD(129, 870) = ( 129 x 870 ) / 37410
= 129 / 870
= 129
Step2:
LCM(3, 456) = 456
GCD(3, 456) = ( 3 x 456 ) / 456
= 3 / 456
= 3
Step3:
LCM(3, 185) = 555
GCD(3, 185) = ( 3 x 185 ) / 555
= 3 / 185
= 3
So, Greatest Common Divisor of 129, 870, 456, 185 is 1
