Given numbers are 278,254,103,219,635

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

The LCM of 278,254,103,219,635 is 3981987210.

Find LCM of 278,254,103,219,635 with Prime Factorization

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

2 x 127 x 139 x 1 x 103 x 219 x 5 = 3981987210

Therefore, the lowest common multiple of 278,254,103,219,635 is 3981987210.

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 254 x 103 x 219 x 635 = 1011424751340

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

254 : 1, 2, 127, 254

103 : 1, 103

219 : 1, 3, 73, 219

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,254,103,219,635, is 1.

Now, the common factors can be found like this.

278:2x 139

254:2x 127

103:103

219:3x 73

635:5x 127

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

2x 127 = 254

Therefore, the value for common factors is 254.

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 = 1011424751340/(1x254)

LCM = 1011424751340/254

LCM = 3981987210

Thus, we can understand that the LCM of 278,254,103,219,635 is 3981987210.
