Given numbers are 390, 779, 621, 776
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 779) = 303810
GCD(390, 779) = ( 390 x 779 ) / 303810
= 390 / 779
= 390
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 776) = 776
GCD(1, 776) = ( 1 x 776 ) / 776
= 1 / 776
= 1
So, Greatest Common Divisor of 390, 779, 621, 776 is 1
