Given numbers are 786,706,430,478

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

The LCM of 786,706,430,478 is 14257179330.

Find LCM of 786,706,430,478 with Prime Factorization

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

2 x 393 x 353 x 215 x 239 = 14257179330

Therefore, the lowest common multiple of 786,706,430,478 is 14257179330.

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.

786 x 706 x 430 x 478 = 114057434640

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

706 : 1, 2, 353, 706

430 : 1, 2, 5, 10, 43, 86, 215, 430

478 : 1, 2, 239, 478

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,706,430,478, is 2.

Now, the common factors can be found like this.

786:2x 3x 131

706:2x 353

430:2x 5x 43

478:2x 239

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 114057434640/(2x4)

LCM = 114057434640/8

LCM = 14257179330

Thus, we can understand that the LCM of 786,706,430,478 is 14257179330.
