Given numbers are 478, 489, 770, 407
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 489) = 233742
GCD(478, 489) = ( 478 x 489 ) / 233742
= 478 / 489
= 478
Step2:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
Step3:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
So, Greatest Common Divisor of 478, 489, 770, 407 is 1
