GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 580) = 96860
GCD(668, 580) = ( 668 x 580 ) / 96860
= 668 / 580
= 668
Step2:
LCM(4, 788) = 788
GCD(4, 788) = ( 4 x 788 ) / 788
= 4 / 788
= 4
Step3:
LCM(4, 147) = 588
GCD(4, 147) = ( 4 x 147 ) / 588
= 4 / 147
= 4
So, Greatest Common Divisor of 668, 580, 788, 147 is 1
