Given numbers are 349,742,316,390

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

The LCM of 349,742,316,390 is 7978495980.

Find LCM of 349,742,316,390 with Prime Factorization

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

2 x 349 x 371 x 158 x 195 = 7978495980

Therefore, the lowest common multiple of 349,742,316,390 is 7978495980.

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.

349 x 742 x 316 x 390 = 31913983920

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.

349 : 1, 349

742 : 1, 2, 7, 14, 53, 106, 371, 742

316 : 1, 2, 4, 79, 158, 316

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 349,742,316,390, is 1.

Now, the common factors can be found like this.

349:349

742:2x 7x 53

316:2x 2x 79

390:2x 3x 5x 13

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 31913983920/(1x4)

LCM = 31913983920/4

LCM = 7978495980

Thus, we can understand that the LCM of 349,742,316,390 is 7978495980.
