Given numbers are 670, 144, 407, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 144) = 48240
GCD(670, 144) = ( 670 x 144 ) / 48240
= 670 / 144
= 670
Step2:
LCM(2, 407) = 814
GCD(2, 407) = ( 2 x 407 ) / 814
= 2 / 407
= 2
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 670, 144, 407, 965 is 1
