Find LCM of 901,870,207,805,420 with Prime Factorization
| 2 | 901, 870, 207, 805, 420 |
| 3 | 901, 435, 207, 805, 210 |
| 5 | 901, 145, 69, 805, 70 |
| 7 | 901, 29, 69, 161, 14 |
| 23 | 901, 29, 69, 23, 2 |
| 901, 29, 3, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 901 x 29 x 3 x 1 x 2 = 757218420
Therefore, the lowest common multiple of 901,870,207,805,420 is 757218420.
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 870 x 207 x 805 x 420 = 54860474529000
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
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
207 : 1, 3, 9, 23, 69, 207
805 : 1, 5, 7, 23, 35, 115, 161, 805
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,870,207,805,420, is 1.
Now, the common factors can be found like this.
901:17x 53
870:2x 3x 5x 29
207:3x 3x 23
805:5x 7x 23
420:2x 2x 3x 5x 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 3x 3x 5x 5x 7x 23 = 72450
Therefore, the value for common factors is 72450.
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 = 54860474529000/(1x72450)
LCM = 54860474529000/72450
LCM = 757218420
Thus, we can understand that the LCM of 901,870,207,805,420 is 757218420.
