Given numbers are 683,287,749

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 683,287,749 is 20974247.

Find LCM of 683,287,749 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

7 x 683 x 41 x 107 = 20974247

Therefore, the lowest common multiple of 683,287,749 is 20974247.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

683 x 287 x 749 = 146819729

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

683 : 1, 683

287 : 1, 7, 41, 287

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,287,749, is 1.

Now, the common factors can be found like this.

683:683

287:7x 41

749:7x 107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7 = 7

Therefore, the value for common factors is 7.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 146819729/(1x7)

LCM = 146819729/7

LCM = 20974247

Thus, we can understand that the LCM of 683,287,749 is 20974247.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 237, 931, 283
