Given numbers are 806, 630, 409, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(806, 630) = 253890
GCD(806, 630) = ( 806 x 630 ) / 253890
= 806 / 630
= 806
Step2:
LCM(2, 409) = 818
GCD(2, 409) = ( 2 x 409 ) / 818
= 2 / 409
= 2
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 806, 630, 409, 489 is 1
