GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(912, 390) = 59280
GCD(912, 390) = ( 912 x 390 ) / 59280
= 912 / 390
= 912
Step2:
LCM(6, 772) = 2316
GCD(6, 772) = ( 6 x 772 ) / 2316
= 6 / 772
= 6
Step3:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
So, Greatest Common Divisor of 912, 390, 772, 249 is 1
