Find LCM of 645,832,475,980,930 with Prime Factorization
| 2 | 645, 832, 475, 980, 930 |
| 2 | 645, 416, 475, 490, 465 |
| 3 | 645, 208, 475, 245, 465 |
| 5 | 215, 208, 475, 245, 155 |
| 43, 208, 95, 49, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 208 x 95 x 49 x 31 = 77439835200
Therefore, the lowest common multiple of 645,832,475,980,930 is 77439835200.
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.
645 x 832 x 475 x 980 x 930 = 232319505600000
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
475 : 1, 5, 19, 25, 95, 475
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,832,475,980,930, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
832:2x 2x 2x 2x 2x 2x 13
475:5x 5x 19
980:2x 2x 5x 7x 7
930:2x 3x 5x 31
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 3x 5x 5x 5 = 3000
Therefore, the value for common factors is 3000.
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 = 232319505600000/(1x3000)
LCM = 232319505600000/3000
LCM = 77439835200
Thus, we can understand that the LCM of 645,832,475,980,930 is 77439835200.
