Given numbers are 420,452,946,236

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

The LCM of 420,452,946,236 is 1324466220.

Find LCM of 420,452,946,236 with Prime Factorization

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

2 x 2 x 105 x 113 x 473 x 59 = 1324466220

Therefore, the lowest common multiple of 420,452,946,236 is 1324466220.

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.

420 x 452 x 946 x 236 = 42382919040

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.

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

452 : 1, 2, 4, 113, 226, 452

946 : 1, 2, 11, 22, 43, 86, 473, 946

236 : 1, 2, 4, 59, 118, 236

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,452,946,236, is 2.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

452:2x 2x 113

946:2x 11x 43

236:2x 2x 59

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 2 = 16

Therefore, the value for common factors is 16.

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 = 42382919040/(2x16)

LCM = 42382919040/32

LCM = 1324466220

Thus, we can understand that the LCM of 420,452,946,236 is 1324466220.
