GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(655, 997) = 653035
GCD(655, 997) = ( 655 x 997 ) / 653035
= 655 / 997
= 655
Step2:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
Step3:
LCM(1, 822) = 822
GCD(1, 822) = ( 1 x 822 ) / 822
= 1 / 822
= 1
So, Greatest Common Divisor of 655, 997, 520, 822 is 1
