Given numbers are 638,292,147,830,803

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

The LCM of 638,292,147,830,803 is 5682493740.

Find LCM of 638,292,147,830,803 with Prime Factorization

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

2 x 11 x 73 x 29 x 2 x 147 x 415 x 1 = 5682493740

Therefore, the lowest common multiple of 638,292,147,830,803 is 5682493740.

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.

638 x 292 x 147 x 830 x 803 = 18252169892880

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

292 : 1, 2, 4, 73, 146, 292

147 : 1, 3, 7, 21, 49, 147

830 : 1, 2, 5, 10, 83, 166, 415, 830

803 : 1, 11, 73, 803

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,292,147,830,803, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

292:2x 2x 73

147:3x 7x 7

830:2x 5x 83

803:11x 73

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

2x 2x 11x 73 = 3212

Therefore, the value for common factors is 3212.

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 = 18252169892880/(1x3212)

LCM = 18252169892880/3212

LCM = 5682493740

Thus, we can understand that the LCM of 638,292,147,830,803 is 5682493740.
