Given numbers are 820, 858, 417, 479
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 858) = 351780
GCD(820, 858) = ( 820 x 858 ) / 351780
= 820 / 858
= 820
Step2:
LCM(2, 417) = 834
GCD(2, 417) = ( 2 x 417 ) / 834
= 2 / 417
= 2
Step3:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
So, Greatest Common Divisor of 820, 858, 417, 479 is 1
