The LCM of 581,191,175,420,756 is 299621700.
Find LCM of 581,191,175,420,756 with Prime Factorization
| 2 | 581, 191, 175, 420, 756 |
| 2 | 581, 191, 175, 210, 378 |
| 3 | 581, 191, 175, 105, 189 |
| 5 | 581, 191, 175, 35, 63 |
| 7 | 581, 191, 7, 35, 63 |
| 83, 191, 1, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 83 x 191 x 1 x 5 x 9 = 299621700
Therefore, the lowest common multiple of 581,191,175,420,756 is 299621700.
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.
581 x 191 x 175 x 420 x 756 = 6166214586000
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.
581 : 1, 7, 83, 581
191 : 1, 191
175 : 1, 5, 7, 25, 35, 175
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
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,191,175,420,756, is 1.
Now, the common factors can be found like this.
581:7x 83
191:191
175:5x 5x 7
420:2x 2x 3x 5x 7
756:2x 2x 3x 3x 3x 7
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 5x 7x 7x 7 = 20580
Therefore, the value for common factors is 20580.
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 = 6166214586000/(1x20580)
LCM = 6166214586000/20580
LCM = 299621700
Thus, we can understand that the LCM of 581,191,175,420,756 is 299621700.
