Find LCM of 102,945,680,802,419 with Prime Factorization


2 102, 945, 680, 802, 419
3 51, 945, 340, 401, 419
5 17, 315, 340, 401, 419
17 17, 63, 68, 401, 419
1, 63, 4, 401, 419

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

2 x 3 x 5 x 17 x 1 x 63 x 4 x 401 x 419 = 21593801880

Therefore, the lowest common multiple of 102,945,680,802,419 is 21593801880.

LCM Formula to Find Lowest Common Multiple of 102,945,680,802,419

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.

102 x 945 x 680 x 802 x 419 = 22025677917600

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.

102 : 1, 2, 3, 6, 17, 34, 51, 102

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

802 : 1, 2, 401, 802

419 : 1, 419

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,945,680,802,419, is 1.

Now, the common factors can be found like this.

102:2x 3x 17

945:3x 3x 3x 5x 7

680:2x 2x 2x 5x 17

802:2x 401

419:419

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 3x 5x 17 = 1020

Therefore, the value for common factors is 1020.

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 = 22025677917600/(1x1020)

LCM = 22025677917600/1020

LCM = 21593801880

Thus, we can understand that the LCM of 102,945,680,802,419 is 21593801880.
