Given numbers are 644,565,452,698

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

The LCM of 644,565,452,698 is 126987140.

Find LCM of 644,565,452,698 with Prime Factorization

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

2 x 2 x 113 x 161 x 5 x 1 x 349 = 126987140

Therefore, the lowest common multiple of 644,565,452,698 is 126987140.

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.

644 x 565 x 452 x 698 = 114796374560

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

565 : 1, 5, 113, 565

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

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,565,452,698, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

565:5x 113

452:2x 2x 113

698:2x 349

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 113 = 904

Therefore, the value for common factors is 904.

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 = 114796374560/(1x904)

LCM = 114796374560/904

LCM = 126987140

Thus, we can understand that the LCM of 644,565,452,698 is 126987140.
