Given numbers are 403,153,391

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

The LCM of 403,153,391 is 1418157.

Find LCM of 403,153,391 with Prime Factorization

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

17 x 403 x 9 x 23 = 1418157

Therefore, the lowest common multiple of 403,153,391 is 1418157.

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.

403 x 153 x 391 = 24108669

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.

403 : 1, 13, 31, 403

153 : 1, 3, 9, 17, 51, 153

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,153,391, is 1.

Now, the common factors can be found like this.

403:13x 31

153:3x 3x 17

391:17x 23

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

17 = 17

Therefore, the value for common factors is 17.

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 = 24108669/(1x17)

LCM = 24108669/17

LCM = 1418157

Thus, we can understand that the LCM of 403,153,391 is 1418157.

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

• LCM of 280, 171, 119
• LCM of 958, 558, 566
• LCM of 297, 931, 293
