Given numbers are 672,940,720,575

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

The LCM of 672,940,720,575 is 54482400.

Find LCM of 672,940,720,575 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 5 x 14 x 47 x 3 x 115 = 54482400

Therefore, the lowest common multiple of 672,940,720,575 is 54482400.

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 940 x 720 x 575 = 261515520000

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

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

575 : 1, 5, 23, 25, 115, 575

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,940,720,575, is 1.

Now, the common factors can be found like this.

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

940:2x 2x 5x 47

720:2x 2x 2x 2x 3x 3x 5

575:5x 5x 23

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 2x 2x 2x 2x 3x 5x 5 = 4800

Therefore, the value for common factors is 4800.

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 = 261515520000/(1x4800)

LCM = 261515520000/4800

LCM = 54482400

Thus, we can understand that the LCM of 672,940,720,575 is 54482400.
