Given numbers are 668, 780, 299, 494
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 780) = 130260
GCD(668, 780) = ( 668 x 780 ) / 130260
= 668 / 780
= 668
Step2:
LCM(4, 299) = 1196
GCD(4, 299) = ( 4 x 299 ) / 1196
= 4 / 299
= 4
Step3:
LCM(1, 494) = 494
GCD(1, 494) = ( 1 x 494 ) / 494
= 1 / 494
= 1
So, Greatest Common Divisor of 668, 780, 299, 494 is 1
