Given numbers are 148,278,778,220

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

The LCM of 148,278,778,220 is 440137940.

Find LCM of 148,278,778,220 with Prime Factorization

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

2 x 2 x 37 x 139 x 389 x 55 = 440137940

Therefore, the lowest common multiple of 148,278,778,220 is 440137940.

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.

148 x 278 x 778 x 220 = 7042207040

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.

148 : 1, 2, 4, 37, 74, 148

278 : 1, 2, 139, 278

778 : 1, 2, 389, 778

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 148,278,778,220, is 2.

Now, the common factors can be found like this.

148:2x 2x 37

278:2x 139

778:2x 389

220:2x 2x 5x 11

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 2 = 8

Therefore, the value for common factors is 8.

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 = 7042207040/(2x8)

LCM = 7042207040/16

LCM = 440137940

Thus, we can understand that the LCM of 148,278,778,220 is 440137940.
