Given numbers are 662, 574, 780, 779
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 574) = 189994
GCD(662, 574) = ( 662 x 574 ) / 189994
= 662 / 574
= 662
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 779) = 1558
GCD(2, 779) = ( 2 x 779 ) / 1558
= 2 / 779
= 2
So, Greatest Common Divisor of 662, 574, 780, 779 is 1
