Given numbers are 678, 489, 338, 670
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(678, 489) = 110514
GCD(678, 489) = ( 678 x 489 ) / 110514
= 678 / 489
= 678
Step2:
LCM(3, 338) = 1014
GCD(3, 338) = ( 3 x 338 ) / 1014
= 3 / 338
= 3
Step3:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
So, Greatest Common Divisor of 678, 489, 338, 670 is 1
