Calculate the LCM of 693,783,651,480

Given numbers are 693,783,651,480

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

The LCM of 693,783,651,480 is 299043360.

Find LCM of 693,783,651,480 with Prime Factorization


3 693, 783, 651, 480
3 231, 261, 217, 160
7 77, 87, 217, 160
11, 87, 31, 160

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

3 x 3 x 7 x 11 x 87 x 31 x 160 = 299043360

Therefore, the lowest common multiple of 693,783,651,480 is 299043360.

LCM Formula to Find Lowest Common Multiple of 693,783,651,480

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.

693 x 783 x 651 x 480 = 169557585120

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.

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

783 : 1, 3, 9, 27, 29, 87, 261, 783

651 : 1, 3, 7, 21, 31, 93, 217, 651

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,783,651,480, is 3.

Now, the common factors can be found like this.

693:3x 3x 7x 11

783:3x 3x 3x 29

651:3x 7x 31

480:2x 2x 2x 2x 2x 3x 5

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

3x 3x 3x 7 = 189

Therefore, the value for common factors is 189.

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 = 169557585120/(3x189)

LCM = 169557585120/567

LCM = 299043360

Thus, we can understand that the LCM of 693,783,651,480 is 299043360.
