Given numbers are 280,250,638,156,949

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

The LCM of 280,250,638,156,949 is 6357351000.

Find LCM of 280,250,638,156,949 with Prime Factorization

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

2 x 2 x 5 x 13 x 14 x 25 x 319 x 3 x 73 = 6357351000

Therefore, the lowest common multiple of 280,250,638,156,949 is 6357351000.

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.

280 x 250 x 638 x 156 x 949 = 6611645040000

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

250 : 1, 2, 5, 10, 25, 50, 125, 250

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

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

949 : 1, 13, 73, 949

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,250,638,156,949, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

250:2x 5x 5x 5

638:2x 11x 29

156:2x 2x 3x 13

949:13x 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 2x 2x 5x 13 = 1040

Therefore, the value for common factors is 1040.

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 = 6611645040000/(1x1040)

LCM = 6611645040000/1040

LCM = 6357351000

Thus, we can understand that the LCM of 280,250,638,156,949 is 6357351000.
