Answer 1

Step-by-step explanation:

Greatest Common Divisor (GCD) for 385 3003 is 77.

Explanation

The Greatest Common Divisor (GCD), also known as the Greatest Common Factor (GCF), or Highest Common Factor (HCF), of two or more non-zero integers, is the largest positive integer that divides the numbers without a remainder.

In this example:

Factors of 385 are: 1 , 5 , 7 , 11 , 35 , 55 , 77 , 385.

Factors of 3003 are: 1 , 3 , 7 , 11 , 13 , 21 , 33 , 39 , 77 , 91 , 143 , 231 , 273 , 429 , 1001 , 3003.

We see that the Greatest Common Factor (Divisor) is 77.

Least Common Multiple (LCM) for 385 3003 is 15015.

Explanation

The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly. NOTE: to find LCM you first need to know how to find GCD.

Step 1: Find the GCD (Greatest Common Divisor ) of 385 and 3003 which is 77.

Step 2: Multiply the numbers 385 and 3003 together ( 385 * 3003 = 1156155 )

Step 3: Divide the 1156155 with 77. (1156155/77 = 15015)

So, the LCM of 385 and 3003 is 15015.
