Given numbers are 868,772,863,840

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

The LCM of 868,772,863,840 is 4337196360.

Find LCM of 868,772,863,840 with Prime Factorization

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

2 x 2 x 7 x 31 x 193 x 863 x 30 = 4337196360

Therefore, the lowest common multiple of 868,772,863,840 is 4337196360.

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.

868 x 772 x 863 x 840 = 485765992320

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

772 : 1, 2, 4, 193, 386, 772

863 : 1, 863

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,772,863,840, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

772:2x 2x 193

863:863

840:2x 2x 2x 3x 5x 7

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 7 = 112

Therefore, the value for common factors is 112.

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 = 485765992320/(1x112)

LCM = 485765992320/112

LCM = 4337196360

Thus, we can understand that the LCM of 868,772,863,840 is 4337196360.
