Given numbers are 403,526,786,220

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

The LCM of 403,526,786,220 is 9163808940.

Find LCM of 403,526,786,220 with Prime Factorization

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

2 x 403 x 263 x 393 x 110 = 9163808940

Therefore, the lowest common multiple of 403,526,786,220 is 9163808940.

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.

403 x 526 x 786 x 220 = 36655235760

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.

403 : 1, 13, 31, 403

526 : 1, 2, 263, 526

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

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,526,786,220, is 1.

Now, the common factors can be found like this.

403:13x 31

526:2x 263

786:2x 3x 131

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 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 = 36655235760/(1x4)

LCM = 36655235760/4

LCM = 9163808940

Thus, we can understand that the LCM of 403,526,786,220 is 9163808940.
