Prime factors of 609 are 3 x 7 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 840, 125, 399, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 125) = 21000
GCD(840, 125) = ( 840 x 125 ) / 21000
= 840 / 125
= 840
Step2:
LCM(5, 399) = 1995
GCD(5, 399) = ( 5 x 399 ) / 1995
= 5 / 399
= 5
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 840, 125, 399, 609 is 1
