GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 822) = 203034
GCD(247, 822) = ( 247 x 822 ) / 203034
= 247 / 822
= 247
Step2:
LCM(1, 324) = 324
GCD(1, 324) = ( 1 x 324 ) / 324
= 1 / 324
= 1
Step3:
LCM(1, 355) = 355
GCD(1, 355) = ( 1 x 355 ) / 355
= 1 / 355
= 1
So, Greatest Common Divisor of 247, 822, 324, 355 is 1
