Given numbers are 862,537,420,774

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

The LCM of 862,537,420,774 is 4179932820.

Find LCM of 862,537,420,774 with Prime Factorization

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

2 x 3 x 431 x 179 x 70 x 129 = 4179932820

Therefore, the lowest common multiple of 862,537,420,774 is 4179932820.

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.

862 x 537 x 420 x 774 = 150477581520

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.

862 : 1, 2, 431, 862

537 : 1, 3, 179, 537

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,537,420,774, is 1.

Now, the common factors can be found like this.

862:2x 431

537:3x 179

420:2x 2x 3x 5x 7

774:2x 3x 3x 43

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 3 = 36

Therefore, the value for common factors is 36.

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 = 150477581520/(1x36)

LCM = 150477581520/36

LCM = 4179932820

Thus, we can understand that the LCM of 862,537,420,774 is 4179932820.
