Find LCM of 504,975,781,896,154 with Prime Factorization
| 2 | 504, 975, 781, 896, 154 |
| 2 | 252, 975, 781, 448, 77 |
| 2 | 126, 975, 781, 224, 77 |
| 3 | 63, 975, 781, 112, 77 |
| 7 | 21, 325, 781, 112, 77 |
| 11 | 3, 325, 781, 16, 11 |
| 3, 325, 71, 16, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 11 x 3 x 325 x 71 x 16 x 1 = 2046844800
Therefore, the lowest common multiple of 504,975,781,896,154 is 2046844800.
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.
504 x 975 x 781 x 896 x 154 = 52955968665600
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
781 : 1, 11, 71, 781
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,975,781,896,154, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
975:3x 5x 5x 13
781:11x 71
896:2x 2x 2x 2x 2x 2x 2x 7
154:2x 7x 11
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 3x 7x 7x 11 = 25872
Therefore, the value for common factors is 25872.
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 = 52955968665600/(1x25872)
LCM = 52955968665600/25872
LCM = 2046844800
Thus, we can understand that the LCM of 504,975,781,896,154 is 2046844800.
