Calculate the LCM of 689,334,351,618

Given numbers are 689,334,351,618

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

The LCM of 689,334,351,618 is 639980406.

Find LCM of 689,334,351,618 with Prime Factorization


2 689, 334, 351, 618
3 689, 167, 351, 309
13 689, 167, 117, 103
53, 167, 9, 103

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

2 x 3 x 13 x 53 x 167 x 9 x 103 = 639980406

Therefore, the lowest common multiple of 689,334,351,618 is 639980406.

LCM Formula to Find Lowest Common Multiple of 689,334,351,618

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.

689 x 334 x 351 x 618 = 49918471668

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.

689 : 1, 13, 53, 689

334 : 1, 2, 167, 334

351 : 1, 3, 9, 13, 27, 39, 117, 351

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,334,351,618, is 1.

Now, the common factors can be found like this.

689:13x 53

334:2x 167

351:3x 3x 3x 13

618:2x 3x 103

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

2x 3x 13 = 78

Therefore, the value for common factors is 78.

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 = 49918471668/(1x78)

LCM = 49918471668/78

LCM = 639980406

Thus, we can understand that the LCM of 689,334,351,618 is 639980406.
