Given numbers are 822, 680, 171, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 680) = 279480
GCD(822, 680) = ( 822 x 680 ) / 279480
= 822 / 680
= 822
Step2:
LCM(2, 171) = 342
GCD(2, 171) = ( 2 x 171 ) / 342
= 2 / 171
= 2
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 822, 680, 171, 220 is 1
