Find LCM of 991,801,175,619,630 with Prime Factorization
| 3 | 991, 801, 175, 619, 630 |
| 3 | 991, 267, 175, 619, 210 |
| 5 | 991, 89, 175, 619, 70 |
| 7 | 991, 89, 35, 619, 14 |
| 991, 89, 5, 619, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 991 x 89 x 5 x 619 x 2 = 171974820150
Therefore, the lowest common multiple of 991,801,175,619,630 is 171974820150.
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.
991 x 801 x 175 x 619 x 630 = 54172068347250
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.
991 : 1, 991
801 : 1, 3, 9, 89, 267, 801
175 : 1, 5, 7, 25, 35, 175
619 : 1, 619
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,801,175,619,630, is 1.
Now, the common factors can be found like this.
991:991
801:3x 3x 89
175:5x 5x 7
619:619
630:2x 3x 3x 5x 7
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 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 54172068347250/(1x315)
LCM = 54172068347250/315
LCM = 171974820150
Thus, we can understand that the LCM of 991,801,175,619,630 is 171974820150.
