Find LCM of 840,787,624,119,962 with Prime Factorization
| 2 | 840, 787, 624, 119, 962 |
| 2 | 420, 787, 312, 119, 481 |
| 2 | 210, 787, 156, 119, 481 |
| 3 | 105, 787, 78, 119, 481 |
| 7 | 35, 787, 26, 119, 481 |
| 13 | 5, 787, 26, 17, 481 |
| 5, 787, 2, 17, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 13 x 5 x 787 x 2 x 17 x 37 = 10811302320
Therefore, the lowest common multiple of 840,787,624,119,962 is 10811302320.
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.
840 x 787 x 624 x 119 x 962 = 47223768533760
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.
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
787 : 1, 787
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
119 : 1, 7, 17, 119
962 : 1, 2, 13, 26, 37, 74, 481, 962
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,787,624,119,962, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
787:787
624:2x 2x 2x 2x 3x 13
119:7x 17
962:2x 13x 37
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 3x 7x 13 = 4368
Therefore, the value for common factors is 4368.
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 = 47223768533760/(1x4368)
LCM = 47223768533760/4368
LCM = 10811302320
Thus, we can understand that the LCM of 840,787,624,119,962 is 10811302320.
