GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(351, 991) = 347841
GCD(351, 991) = ( 351 x 991 ) / 347841
= 351 / 991
= 351
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 553) = 553
GCD(1, 553) = ( 1 x 553 ) / 553
= 1 / 553
= 1
So, Greatest Common Divisor of 351, 991, 391, 553 is 1
