Find LCM of 911,817,213,549,639 with Prime Factorization
| 3 | 911, 817, 213, 549, 639 |
| 3 | 911, 817, 71, 183, 213 |
| 71 | 911, 817, 71, 61, 71 |
| 911, 817, 1, 61, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 71 x 911 x 817 x 1 x 61 x 1 = 29011562973
Therefore, the lowest common multiple of 911,817,213,549,639 is 29011562973.
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.
911 x 817 x 213 x 549 x 639 = 55615166219241
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.
911 : 1, 911
817 : 1, 19, 43, 817
213 : 1, 3, 71, 213
549 : 1, 3, 9, 61, 183, 549
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,817,213,549,639, is 1.
Now, the common factors can be found like this.
911:911
817:19x 43
213:3x 71
549:3x 3x 61
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 71 = 1917
Therefore, the value for common factors is 1917.
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 = 55615166219241/(1x1917)
LCM = 55615166219241/1917
LCM = 29011562973
Thus, we can understand that the LCM of 911,817,213,549,639 is 29011562973.
