Find LCM of 901,680,856,620,969 with Prime Factorization
| 2 | 901, 680, 856, 620, 969 |
| 2 | 901, 340, 428, 310, 969 |
| 2 | 901, 170, 214, 155, 969 |
| 5 | 901, 85, 107, 155, 969 |
| 17 | 901, 17, 107, 31, 969 |
| 53, 1, 107, 31, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 53 x 1 x 107 x 31 x 57 = 6814046760
Therefore, the lowest common multiple of 901,680,856,620,969 is 6814046760.
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.
901 x 680 x 856 x 620 x 969 = 315081522182400
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.
901 : 1, 17, 53, 901
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
856 : 1, 2, 4, 8, 107, 214, 428, 856
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,680,856,620,969, is 1.
Now, the common factors can be found like this.
901:17x 53
680:2x 2x 2x 5x 17
856:2x 2x 2x 107
620:2x 2x 5x 31
969:3x 17x 19
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 5x 17x 17 = 46240
Therefore, the value for common factors is 46240.
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 = 315081522182400/(1x46240)
LCM = 315081522182400/46240
LCM = 6814046760
Thus, we can understand that the LCM of 901,680,856,620,969 is 6814046760.
