Given numbers are 444, 390, 372, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(444, 390) = 28860
GCD(444, 390) = ( 444 x 390 ) / 28860
= 444 / 390
= 444
Step2:
LCM(6, 372) = 372
GCD(6, 372) = ( 6 x 372 ) / 372
= 6 / 372
= 6
Step3:
LCM(6, 780) = 780
GCD(6, 780) = ( 6 x 780 ) / 780
= 6 / 780
= 6
So, Greatest Common Divisor of 444, 390, 372, 780 is 6
