Given numbers are 654, 195, 605, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(654, 195) = 42510
GCD(654, 195) = ( 654 x 195 ) / 42510
= 654 / 195
= 654
Step2:
LCM(3, 605) = 1815
GCD(3, 605) = ( 3 x 605 ) / 1815
= 3 / 605
= 3
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 654, 195, 605, 630 is 1
