Calculate the LCM of 441,671,442,402

Given numbers are 441,671,442,402

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

The LCM of 441,671,442,402 is 8763108354.

Find LCM of 441,671,442,402 with Prime Factorization


2 441, 671, 442, 402
3 441, 671, 221, 201
147, 671, 221, 67

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

2 x 3 x 147 x 671 x 221 x 67 = 8763108354

Therefore, the lowest common multiple of 441,671,442,402 is 8763108354.

LCM Formula to Find Lowest Common Multiple of 441,671,442,402

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.

441 x 671 x 442 x 402 = 52578650124

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.

441 : 1, 3, 7, 9, 21, 49, 63, 147, 441

671 : 1, 11, 61, 671

442 : 1, 2, 13, 17, 26, 34, 221, 442

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,671,442,402, is 1.

Now, the common factors can be found like this.

441:3x 3x 7x 7

671:11x 61

442:2x 13x 17

402:2x 3x 67

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 52578650124/(1x6)

LCM = 52578650124/6

LCM = 8763108354

Thus, we can understand that the LCM of 441,671,442,402 is 8763108354.
