Given numbers are 705, 618, 665, 822
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 618) = 145230
GCD(705, 618) = ( 705 x 618 ) / 145230
= 705 / 618
= 705
Step2:
LCM(3, 665) = 1995
GCD(3, 665) = ( 3 x 665 ) / 1995
= 3 / 665
= 3
Step3:
LCM(1, 822) = 822
GCD(1, 822) = ( 1 x 822 ) / 822
= 1 / 822
= 1
So, Greatest Common Divisor of 705, 618, 665, 822 is 1
