Find LCM of 577,252,742,540,991 with Prime Factorization
| 2 | 577, 252, 742, 540, 991 |
| 2 | 577, 126, 371, 270, 991 |
| 3 | 577, 63, 371, 135, 991 |
| 3 | 577, 21, 371, 45, 991 |
| 7 | 577, 7, 371, 15, 991 |
| 577, 1, 53, 15, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 577 x 1 x 53 x 15 x 991 = 114555814380
Therefore, the lowest common multiple of 577,252,742,540,991 is 114555814380.
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.
577 x 252 x 742 x 540 x 991 = 57736130447520
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.
577 : 1, 577
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
742 : 1, 2, 7, 14, 53, 106, 371, 742
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 577,252,742,540,991, is 1.
Now, the common factors can be found like this.
577:577
252:2x 2x 3x 3x 7
742:2x 7x 53
540:2x 2x 3x 3x 3x 5
991:991
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 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 57736130447520/(1x504)
LCM = 57736130447520/504
LCM = 114555814380
Thus, we can understand that the LCM of 577,252,742,540,991 is 114555814380.
