Given numbers are 390, 354, 844, 665
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 354) = 23010
GCD(390, 354) = ( 390 x 354 ) / 23010
= 390 / 354
= 390
Step2:
LCM(6, 844) = 2532
GCD(6, 844) = ( 6 x 844 ) / 2532
= 6 / 844
= 6
Step3:
LCM(2, 665) = 1330
GCD(2, 665) = ( 2 x 665 ) / 1330
= 2 / 665
= 2
So, Greatest Common Divisor of 390, 354, 844, 665 is 1
