GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(294, 310) = 45570
GCD(294, 310) = ( 294 x 310 ) / 45570
= 294 / 310
= 294
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 654) = 654
GCD(2, 654) = ( 2 x 654 ) / 654
= 2 / 654
= 2
So, Greatest Common Divisor of 294, 310, 780, 654 is 2
