Find LCM of 918,972,254,771,820 with Prime Factorization
| 2 | 918, 972, 254, 771, 820 |
| 2 | 459, 486, 127, 771, 410 |
| 3 | 459, 243, 127, 771, 205 |
| 3 | 153, 81, 127, 257, 205 |
| 3 | 51, 27, 127, 257, 205 |
| 17, 9, 127, 257, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 17 x 9 x 127 x 257 x 205 = 110562001380
Therefore, the lowest common multiple of 918,972,254,771,820 is 110562001380.
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.
918 x 972 x 254 x 771 x 820 = 143288353788480
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
254 : 1, 2, 127, 254
771 : 1, 3, 257, 771
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,972,254,771,820, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
972:2x 2x 3x 3x 3x 3x 3
254:2x 127
771:3x 257
820:2x 2x 5x 41
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 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 143288353788480/(1x1296)
LCM = 143288353788480/1296
LCM = 110562001380
Thus, we can understand that the LCM of 918,972,254,771,820 is 110562001380.
