Given numbers are 435,278,145,653

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

The LCM of 435,278,145,653 is 78967290.

Find LCM of 435,278,145,653 with Prime Factorization

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

5 x 29 x 3 x 278 x 1 x 653 = 78967290

Therefore, the lowest common multiple of 435,278,145,653 is 78967290.

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.

435 x 278 x 145 x 653 = 11450257050

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.

435 : 1, 3, 5, 15, 29, 87, 145, 435

278 : 1, 2, 139, 278

145 : 1, 5, 29, 145

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 435,278,145,653, is 1.

Now, the common factors can be found like this.

435:3x 5x 29

278:2x 139

145:5x 29

653:653

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

5x 29 = 145

Therefore, the value for common factors is 145.

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 = 11450257050/(1x145)

LCM = 11450257050/145

LCM = 78967290

Thus, we can understand that the LCM of 435,278,145,653 is 78967290.
