GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 387) = 126162
GCD(978, 387) = ( 978 x 387 ) / 126162
= 978 / 387
= 978
Step2:
LCM(3, 352) = 1056
GCD(3, 352) = ( 3 x 352 ) / 1056
= 3 / 352
= 3
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 978, 387, 352, 518 is 1
