Given numbers are 672,221,190,399,402

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

The LCM of 672,221,190,399,402 is 945278880.

Find LCM of 672,221,190,399,402 with Prime Factorization

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

2 x 3 x 7 x 19 x 16 x 221 x 5 x 1 x 67 = 945278880

Therefore, the lowest common multiple of 672,221,190,399,402 is 945278880.

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.

672 x 221 x 190 x 399 x 402 = 4525995277440

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

221 : 1, 13, 17, 221

190 : 1, 2, 5, 10, 19, 38, 95, 190

399 : 1, 3, 7, 19, 21, 57, 133, 399

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,221,190,399,402, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

221:13x 17

190:2x 5x 19

399:3x 7x 19

402:2x 3x 67

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 3x 7x 19 = 4788

Therefore, the value for common factors is 4788.

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 = 4525995277440/(1x4788)

LCM = 4525995277440/4788

LCM = 945278880

Thus, we can understand that the LCM of 672,221,190,399,402 is 945278880.
