GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(791, 276) = 218316
GCD(791, 276) = ( 791 x 276 ) / 218316
= 791 / 276
= 791
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
= 1 / 278
= 1
So, Greatest Common Divisor of 791, 276, 387, 278 is 1
