Given numbers are 330, 780, 586, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(330, 780) = 8580
GCD(330, 780) = ( 330 x 780 ) / 8580
= 330 / 780
= 330
Step2:
LCM(30, 586) = 8790
GCD(30, 586) = ( 30 x 586 ) / 8790
= 30 / 586
= 30
Step3:
LCM(2, 455) = 910
GCD(2, 455) = ( 2 x 455 ) / 910
= 2 / 455
= 2
So, Greatest Common Divisor of 330, 780, 586, 455 is 1
