Given numbers are 109, 245, 630, 324
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(109, 245) = 26705
GCD(109, 245) = ( 109 x 245 ) / 26705
= 109 / 245
= 109
Step2:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
Step3:
LCM(1, 324) = 324
GCD(1, 324) = ( 1 x 324 ) / 324
= 1 / 324
= 1
So, Greatest Common Divisor of 109, 245, 630, 324 is 1
