Given numbers are 702,321,145,160,406

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

The LCM of 702,321,145,160,406 is 1219851360.

Find LCM of 702,321,145,160,406 with Prime Factorization

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

2 x 3 x 5 x 29 x 117 x 107 x 1 x 16 x 7 = 1219851360

Therefore, the lowest common multiple of 702,321,145,160,406 is 1219851360.

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.

702 x 321 x 145 x 160 x 406 = 2122541366400

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.

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

321 : 1, 3, 107, 321

145 : 1, 5, 29, 145

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,321,145,160,406, is 1.

Now, the common factors can be found like this.

702:2x 3x 3x 3x 13

321:3x 107

145:5x 29

160:2x 2x 2x 2x 2x 5

406:2x 7x 29

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 3x 5x 29 = 1740

Therefore, the value for common factors is 1740.

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 = 2122541366400/(1x1740)

LCM = 2122541366400/1740

LCM = 1219851360

Thus, we can understand that the LCM of 702,321,145,160,406 is 1219851360.
