Find LCM of 870,650,308,121,784 with Prime Factorization
| 2 | 870, 650, 308, 121, 784 |
| 2 | 435, 325, 154, 121, 392 |
| 5 | 435, 325, 77, 121, 196 |
| 7 | 87, 65, 77, 121, 196 |
| 11 | 87, 65, 11, 121, 28 |
| 87, 65, 1, 11, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 87 x 65 x 1 x 11 x 28 = 2682279600
Therefore, the lowest common multiple of 870,650,308,121,784 is 2682279600.
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.
870 x 650 x 308 x 121 x 784 = 16522842336000
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
121 : 1, 11, 121
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,650,308,121,784, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
650:2x 5x 5x 13
308:2x 2x 7x 11
121:11x 11
784:2x 2x 2x 2x 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 2x 5x 7x 11 = 6160
Therefore, the value for common factors is 6160.
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 = 16522842336000/(1x6160)
LCM = 16522842336000/6160
LCM = 2682279600
Thus, we can understand that the LCM of 870,650,308,121,784 is 2682279600.
