Given numbers are 390, 815, 694, 297
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 815) = 63570
GCD(390, 815) = ( 390 x 815 ) / 63570
= 390 / 815
= 390
Step2:
LCM(5, 694) = 3470
GCD(5, 694) = ( 5 x 694 ) / 3470
= 5 / 694
= 5
Step3:
LCM(1, 297) = 297
GCD(1, 297) = ( 1 x 297 ) / 297
= 1 / 297
= 1
So, Greatest Common Divisor of 390, 815, 694, 297 is 1
