Find LCM of 978,931,167,105,370 with Prime Factorization
| 2 | 978, 931, 167, 105, 370 |
| 3 | 489, 931, 167, 105, 185 |
| 5 | 163, 931, 167, 35, 185 |
| 7 | 163, 931, 167, 7, 37 |
| 163, 133, 167, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 163 x 133 x 167 x 1 x 37 = 28130453610
Therefore, the lowest common multiple of 978,931,167,105,370 is 28130453610.
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.
978 x 931 x 167 x 105 x 370 = 5907395258100
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
931 : 1, 7, 19, 49, 133, 931
167 : 1, 167
105 : 1, 3, 5, 7, 15, 21, 35, 105
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,931,167,105,370, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
931:7x 7x 19
167:167
105:3x 5x 7
370:2x 5x 37
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 7 = 210
Therefore, the value for common factors is 210.
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 = 5907395258100/(1x210)
LCM = 5907395258100/210
LCM = 28130453610
Thus, we can understand that the LCM of 978,931,167,105,370 is 28130453610.
