GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 738) = 47970
GCD(390, 738) = ( 390 x 738 ) / 47970
= 390 / 738
= 390
Step2:
LCM(6, 947) = 5682
GCD(6, 947) = ( 6 x 947 ) / 5682
= 6 / 947
= 6
Step3:
LCM(1, 396) = 396
GCD(1, 396) = ( 1 x 396 ) / 396
= 1 / 396
= 1
So, Greatest Common Divisor of 390, 738, 947, 396 is 1
