Given numbers are 786,721,211,860

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

The LCM of 786,721,211,860 is 51417235380.

Find LCM of 786,721,211,860 with Prime Factorization

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

2 x 393 x 721 x 211 x 430 = 51417235380

Therefore, the lowest common multiple of 786,721,211,860 is 51417235380.

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.

786 x 721 x 211 x 860 = 102834470760

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

721 : 1, 7, 103, 721

211 : 1, 211

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,721,211,860, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

721:7x 103

211:211

860:2x 2x 5x 43

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 102834470760/(1x2)

LCM = 102834470760/2

LCM = 51417235380

Thus, we can understand that the LCM of 786,721,211,860 is 51417235380.
