Calculate the LCM of 760,612,783,686

Given numbers are 760,612,783,686

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

The LCM of 760,612,783,686 is 3469911480.

Find LCM of 760,612,783,686 with Prime Factorization


2 760, 612, 783, 686
2 380, 306, 783, 343
3 190, 153, 783, 343
3 190, 51, 261, 343
190, 17, 87, 343

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

2 x 2 x 3 x 3 x 190 x 17 x 87 x 343 = 3469911480

Therefore, the lowest common multiple of 760,612,783,686 is 3469911480.

LCM Formula to Find Lowest Common Multiple of 760,612,783,686

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.

760 x 612 x 783 x 686 = 249833626560

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.

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,612,783,686, is 1.

Now, the common factors can be found like this.

760:2x 2x 2x 5x 19

612:2x 2x 3x 3x 17

783:3x 3x 3x 29

686:2x 7x 7x 7

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 249833626560/(1x72)

LCM = 249833626560/72

LCM = 3469911480

Thus, we can understand that the LCM of 760,612,783,686 is 3469911480.
