Find LCM of 785,257,220,440,124 with Prime Factorization
2 | 785, 257, 220, 440, 124 |
2 | 785, 257, 110, 220, 62 |
5 | 785, 257, 55, 110, 31 |
11 | 157, 257, 11, 22, 31 |
157, 257, 1, 2, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 157 x 257 x 1 x 2 x 31 = 550360360
Therefore, the lowest common multiple of 785,257,220,440,124 is 550360360.
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.
785 x 257 x 220 x 440 x 124 = 2421585584000
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.
785 : 1, 5, 157, 785
257 : 1, 257
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,257,220,440,124, is 1.
Now, the common factors can be found like this.
785:5x 157
257:257
220:2x 2x 5x 11
440:2x 2x 2x 5x 11
124:2x 2x 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 2x 5x 5x 11 = 4400
Therefore, the value for common factors is 4400.
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 = 2421585584000/(1x4400)
LCM = 2421585584000/4400
LCM = 550360360
Thus, we can understand that the LCM of 785,257,220,440,124 is 550360360.
