Find LCM of 931,420,740,291,753 with Prime Factorization
| 2 | 931, 420, 740, 291, 753 |
| 2 | 931, 210, 370, 291, 753 |
| 3 | 931, 105, 185, 291, 753 |
| 5 | 931, 35, 185, 97, 251 |
| 7 | 931, 7, 37, 97, 251 |
| 133, 1, 37, 97, 251 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 133 x 1 x 37 x 97 x 251 = 50320866540
Therefore, the lowest common multiple of 931,420,740,291,753 is 50320866540.
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.
931 x 420 x 740 x 291 x 753 = 63404291840400
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.
931 : 1, 7, 19, 49, 133, 931
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
291 : 1, 3, 97, 291
753 : 1, 3, 251, 753
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,420,740,291,753, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
420:2x 2x 3x 5x 7
740:2x 2x 5x 37
291:3x 97
753:3x 251
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 63404291840400/(1x1260)
LCM = 63404291840400/1260
LCM = 50320866540
Thus, we can understand that the LCM of 931,420,740,291,753 is 50320866540.
