Given numbers are 665, 235, 140, 421
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 235) = 31255
GCD(665, 235) = ( 665 x 235 ) / 31255
= 665 / 235
= 665
Step2:
LCM(5, 140) = 140
GCD(5, 140) = ( 5 x 140 ) / 140
= 5 / 140
= 5
Step3:
LCM(5, 421) = 2105
GCD(5, 421) = ( 5 x 421 ) / 2105
= 5 / 421
= 5
So, Greatest Common Divisor of 665, 235, 140, 421 is 1
