Calculate the LCM of 278,850,490

Given numbers are 278,850,490

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

The LCM of 278,850,490 is 5789350.

Find LCM of 278,850,490 with Prime Factorization


2 278, 850, 490
5 139, 425, 245
139, 85, 49

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

2 x 5 x 139 x 85 x 49 = 5789350

Therefore, the lowest common multiple of 278,850,490 is 5789350.

LCM Formula to Find Lowest Common Multiple of 278,850,490

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.

278 x 850 x 490 = 115787000

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.

278 : 1, 2, 139, 278

850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,850,490, is 2.

Now, the common factors can be found like this.

278:2x 139

850:2x 5x 5x 17

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 5 = 10

Therefore, the value for common factors is 10.

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 = 115787000/(2x10)

LCM = 115787000/20

LCM = 5789350

Thus, we can understand that the LCM of 278,850,490 is 5789350.
