Given numbers are 665, 120, 210, 103
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 120) = 15960
GCD(665, 120) = ( 665 x 120 ) / 15960
= 665 / 120
= 665
Step2:
LCM(5, 210) = 210
GCD(5, 210) = ( 5 x 210 ) / 210
= 5 / 210
= 5
Step3:
LCM(5, 103) = 515
GCD(5, 103) = ( 5 x 103 ) / 515
= 5 / 103
= 5
So, Greatest Common Divisor of 665, 120, 210, 103 is 1
