Given numbers are 609, 329, 642, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(609, 329) = 28623
GCD(609, 329) = ( 609 x 329 ) / 28623
= 609 / 329
= 609
Step2:
LCM(7, 642) = 4494
GCD(7, 642) = ( 7 x 642 ) / 4494
= 7 / 642
= 7
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 609, 329, 642, 660 is 1
