Given numbers are 430, 657, 309, 609
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 657) = 282510
GCD(430, 657) = ( 430 x 657 ) / 282510
= 430 / 657
= 430
Step2:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
Step3:
LCM(1, 609) = 609
GCD(1, 609) = ( 1 x 609 ) / 609
= 1 / 609
= 1
So, Greatest Common Divisor of 430, 657, 309, 609 is 1
