Given numbers are 524,452,861,421

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

The LCM of 524,452,861,421 is 21463224972.

Find LCM of 524,452,861,421 with Prime Factorization

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

2 x 2 x 131 x 113 x 861 x 421 = 21463224972

Therefore, the lowest common multiple of 524,452,861,421 is 21463224972.

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 452 x 861 x 421 = 85852899888

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

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

861 : 1, 3, 7, 21, 41, 123, 287, 861

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 524,452,861,421, is 1.

Now, the common factors can be found like this.

524:2x 2x 131

452:2x 2x 113

861:3x 7x 41

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 85852899888/(1x4)

LCM = 85852899888/4

LCM = 21463224972

Thus, we can understand that the LCM of 524,452,861,421 is 21463224972.
