Find LCM of 508,420,576,770,931 with Prime Factorization
| 2 | 508, 420, 576, 770, 931 |
| 2 | 254, 210, 288, 385, 931 |
| 3 | 127, 105, 144, 385, 931 |
| 5 | 127, 35, 48, 385, 931 |
| 7 | 127, 7, 48, 77, 931 |
| 127, 1, 48, 11, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 127 x 1 x 48 x 11 x 133 = 3745748160
Therefore, the lowest common multiple of 508,420,576,770,931 is 3745748160.
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.
508 x 420 x 576 x 770 x 931 = 88099996723200
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.
508 : 1, 2, 4, 127, 254, 508
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
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 508,420,576,770,931, is 1.
Now, the common factors can be found like this.
508:2x 2x 127
420:2x 2x 3x 5x 7
576:2x 2x 2x 2x 2x 2x 3x 3
770:2x 5x 7x 11
931:7x 7x 19
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 2x 2x 3x 5x 7x 7 = 23520
Therefore, the value for common factors is 23520.
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 = 88099996723200/(1x23520)
LCM = 88099996723200/23520
LCM = 3745748160
Thus, we can understand that the LCM of 508,420,576,770,931 is 3745748160.
