Find LCM of 845,254,870,143,693 with Prime Factorization
2 | 845, 254, 870, 143, 693 |
3 | 845, 127, 435, 143, 693 |
5 | 845, 127, 145, 143, 231 |
11 | 169, 127, 29, 143, 231 |
13 | 169, 127, 29, 13, 21 |
1, 127, 29, 13, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 1 x 127 x 29 x 13 x 21 = 4313419110
Therefore, the lowest common multiple of 845,254,870,143,693 is 4313419110.
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.
845 x 254 x 870 x 143 x 693 = 18504567981900
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.
845 : 1, 5, 13, 65, 169, 845
254 : 1, 2, 127, 254
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
143 : 1, 11, 13, 143
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,254,870,143,693, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
254:2x 127
870:2x 3x 5x 29
143:11x 13
693:3x 3x 7x 11
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 5x 11x 13 = 4290
Therefore, the value for common factors is 4290.
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 = 18504567981900/(1x4290)
LCM = 18504567981900/4290
LCM = 4313419110
Thus, we can understand that the LCM of 845,254,870,143,693 is 4313419110.
