Given numbers are 490,142,718,783

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

The LCM of 490,142,718,783 is 9779364630.

Find LCM of 490,142,718,783 with Prime Factorization

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

2 x 245 x 71 x 359 x 783 = 9779364630

Therefore, the lowest common multiple of 490,142,718,783 is 9779364630.

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.

490 x 142 x 718 x 783 = 39117458520

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.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

142 : 1, 2, 71, 142

718 : 1, 2, 359, 718

783 : 1, 3, 9, 27, 29, 87, 261, 783

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,142,718,783, is 1.

Now, the common factors can be found like this.

490:2x 5x 7x 7

142:2x 71

718:2x 359

783:3x 3x 3x 29

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 = 39117458520/(1x4)

LCM = 39117458520/4

LCM = 9779364630

Thus, we can understand that the LCM of 490,142,718,783 is 9779364630.
