Given numbers are 129, 345, 670, 104
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 345) = 14835
GCD(129, 345) = ( 129 x 345 ) / 14835
= 129 / 345
= 129
Step2:
LCM(3, 670) = 2010
GCD(3, 670) = ( 3 x 670 ) / 2010
= 3 / 670
= 3
Step3:
LCM(1, 104) = 104
GCD(1, 104) = ( 1 x 104 ) / 104
= 1 / 104
= 1
So, Greatest Common Divisor of 129, 345, 670, 104 is 1
