Given numbers are 440, 642, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 642) = 141240
GCD(440, 642) = ( 440 x 642 ) / 141240
= 440 / 642
= 440
Step2:
LCM(2, 605) = 1210
GCD(2, 605) = ( 2 x 605 ) / 1210
= 2 / 605
= 2
So, Greatest Common Divisor of 440, 642, 605 is 1
