Given numbers are 893,720,703,490

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

The LCM of 893,720,703,490 is 1165686480.

Find LCM of 893,720,703,490 with Prime Factorization

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

2 x 5 x 19 x 47 x 72 x 37 x 49 = 1165686480

Therefore, the lowest common multiple of 893,720,703,490 is 1165686480.

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.

893 x 720 x 703 x 490 = 221480431200

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.

893 : 1, 19, 47, 893

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

703 : 1, 19, 37, 703

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,720,703,490, is 1.

Now, the common factors can be found like this.

893:19x 47

720:2x 2x 2x 2x 3x 3x 5

703:19x 37

490:2x 5x 7x 7

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

2x 5x 19 = 190

Therefore, the value for common factors is 190.

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 = 221480431200/(1x190)

LCM = 221480431200/190

LCM = 1165686480

Thus, we can understand that the LCM of 893,720,703,490 is 1165686480.
