Calculate the LCM of 290,520,578,557

Given numbers are 290,520,578,557

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

The LCM of 290,520,578,557 is 2427472840.

Find LCM of 290,520,578,557 with Prime Factorization


2 290, 520, 578, 557
5 145, 260, 289, 557
29, 52, 289, 557

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

2 x 5 x 29 x 52 x 289 x 557 = 2427472840

Therefore, the lowest common multiple of 290,520,578,557 is 2427472840.

LCM Formula to Find Lowest Common Multiple of 290,520,578,557

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.

290 x 520 x 578 x 557 = 48549456800

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.

290 : 1, 2, 5, 10, 29, 58, 145, 290

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

578 : 1, 2, 17, 34, 289, 578

557 : 1, 557

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,520,578,557, is 1.

Now, the common factors can be found like this.

290:2x 5x 29

520:2x 2x 2x 5x 13

578:2x 17x 17

557:557

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 5 = 20

Therefore, the value for common factors is 20.

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 = 48549456800/(1x20)

LCM = 48549456800/20

LCM = 2427472840

Thus, we can understand that the LCM of 290,520,578,557 is 2427472840.
