Given numbers are 442,507,871,421

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

The LCM of 442,507,871,421 is 486232266.

Find LCM of 442,507,871,421 with Prime Factorization

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

13 x 34 x 39 x 67 x 421 = 486232266

Therefore, the lowest common multiple of 442,507,871,421 is 486232266.

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.

442 x 507 x 871 x 421 = 82173252954

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.

442 : 1, 2, 13, 17, 26, 34, 221, 442

507 : 1, 3, 13, 39, 169, 507

871 : 1, 13, 67, 871

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,507,871,421, is 1.

Now, the common factors can be found like this.

442:2x 13x 17

507:3x 13x 13

871:13x 67

421:421

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 82173252954/(1x169)

LCM = 82173252954/169

LCM = 486232266

Thus, we can understand that the LCM of 442,507,871,421 is 486232266.
