Find LCM of 895,420,972,180,802 with Prime Factorization
| 2 | 895, 420, 972, 180, 802 |
| 2 | 895, 210, 486, 90, 401 |
| 3 | 895, 105, 243, 45, 401 |
| 3 | 895, 35, 81, 15, 401 |
| 5 | 895, 35, 27, 5, 401 |
| 179, 7, 27, 1, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 179 x 7 x 27 x 1 x 401 = 2441921580
Therefore, the lowest common multiple of 895,420,972,180,802 is 2441921580.
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.
895 x 420 x 972 x 180 x 802 = 52745506128000
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.
895 : 1, 5, 179, 895
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
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 895,420,972,180,802, is 1.
Now, the common factors can be found like this.
895:5x 179
420:2x 2x 3x 5x 7
972:2x 2x 3x 3x 3x 3x 3
180:2x 2x 3x 3x 5
802:2x 401
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 3x 3x 3x 5x 5 = 21600
Therefore, the value for common factors is 21600.
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 = 52745506128000/(1x21600)
LCM = 52745506128000/21600
LCM = 2441921580
Thus, we can understand that the LCM of 895,420,972,180,802 is 2441921580.
