Given numbers are 398, 166, 104, 875
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 166) = 33034
GCD(398, 166) = ( 398 x 166 ) / 33034
= 398 / 166
= 398
Step2:
LCM(2, 104) = 104
GCD(2, 104) = ( 2 x 104 ) / 104
= 2 / 104
= 2
Step3:
LCM(2, 875) = 1750
GCD(2, 875) = ( 2 x 875 ) / 1750
= 2 / 875
= 2
So, Greatest Common Divisor of 398, 166, 104, 875 is 1
