Find LCM of 919,840,436,100,694 with Prime Factorization
2 | 919, 840, 436, 100, 694 |
2 | 919, 420, 218, 50, 347 |
5 | 919, 210, 109, 25, 347 |
919, 42, 109, 5, 347 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 919 x 42 x 109 x 5 x 347 = 145989215400
Therefore, the lowest common multiple of 919,840,436,100,694 is 145989215400.
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.
919 x 840 x 436 x 100 x 694 = 23358274464000
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.
919 : 1, 919
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
436 : 1, 2, 4, 109, 218, 436
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
694 : 1, 2, 347, 694
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,840,436,100,694, is 1.
Now, the common factors can be found like this.
919:919
840:2x 2x 2x 3x 5x 7
436:2x 2x 109
100:2x 2x 5x 5
694:2x 347
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 23358274464000/(1x160)
LCM = 23358274464000/160
LCM = 145989215400
Thus, we can understand that the LCM of 919,840,436,100,694 is 145989215400.
