Given numbers are 524,840,661,275,420

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

The LCM of 524,840,661,275,420 is 4000504200.

Find LCM of 524,840,661,275,420 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 131 x 1 x 661 x 55 x 2 = 4000504200

Therefore, the lowest common multiple of 524,840,661,275,420 is 4000504200.

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.

524 x 840 x 661 x 275 x 420 = 33604235280000

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.

524 : 1, 2, 4, 131, 262, 524

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

661 : 1, 661

275 : 1, 5, 11, 25, 55, 275

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,840,661,275,420, is 1.

Now, the common factors can be found like this.

524:2x 2x 131

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

661:661

275:5x 5x 11

420:2x 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 3x 5x 5x 7 = 8400

Therefore, the value for common factors is 8400.

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 = 33604235280000/(1x8400)

LCM = 33604235280000/8400

LCM = 4000504200

Thus, we can understand that the LCM of 524,840,661,275,420 is 4000504200.
