Given numbers are 720,128,694,133

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

The LCM of 720,128,694,133 is 265829760.

Find LCM of 720,128,694,133 with Prime Factorization

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

2 x 2 x 2 x 2 x 45 x 8 x 347 x 133 = 265829760

Therefore, the lowest common multiple of 720,128,694,133 is 265829760.

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.

720 x 128 x 694 x 133 = 8506552320

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.

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

128 : 1, 2, 4, 8, 16, 32, 64, 128

694 : 1, 2, 347, 694

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,128,694,133, is 1.

Now, the common factors can be found like this.

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

128:2x 2x 2x 2x 2x 2x 2

694:2x 347

133:7x 19

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 2 = 32

Therefore, the value for common factors is 32.

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 = 8506552320/(1x32)

LCM = 8506552320/32

LCM = 265829760

Thus, we can understand that the LCM of 720,128,694,133 is 265829760.
