Given numbers are 858, 489, 564, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 489) = 139854
GCD(858, 489) = ( 858 x 489 ) / 139854
= 858 / 489
= 858
Step2:
LCM(3, 564) = 564
GCD(3, 564) = ( 3 x 564 ) / 564
= 3 / 564
= 3
Step3:
LCM(3, 820) = 2460
GCD(3, 820) = ( 3 x 820 ) / 2460
= 3 / 820
= 3
So, Greatest Common Divisor of 858, 489, 564, 820 is 1
