Given numbers are 390, 962, 438, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 962) = 14430
GCD(390, 962) = ( 390 x 962 ) / 14430
= 390 / 962
= 390
Step2:
LCM(26, 438) = 5694
GCD(26, 438) = ( 26 x 438 ) / 5694
= 26 / 438
= 26
Step3:
LCM(2, 831) = 1662
GCD(2, 831) = ( 2 x 831 ) / 1662
= 2 / 831
= 2
So, Greatest Common Divisor of 390, 962, 438, 831 is 1
