Find LCM of 423,777,905,490,302 with Prime Factorization
| 2 | 423, 777, 905, 490, 302 |
| 3 | 423, 777, 905, 245, 151 |
| 5 | 141, 259, 905, 245, 151 |
| 7 | 141, 259, 181, 49, 151 |
| 141, 37, 181, 7, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 141 x 37 x 181 x 7 x 151 = 209601165690
Therefore, the lowest common multiple of 423,777,905,490,302 is 209601165690.
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.
423 x 777 x 905 x 490 x 302 = 44016244794900
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.
423 : 1, 3, 9, 47, 141, 423
777 : 1, 3, 7, 21, 37, 111, 259, 777
905 : 1, 5, 181, 905
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
302 : 1, 2, 151, 302
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,777,905,490,302, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
777:3x 7x 37
905:5x 181
490:2x 5x 7x 7
302:2x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 44016244794900/(1x210)
LCM = 44016244794900/210
LCM = 209601165690
Thus, we can understand that the LCM of 423,777,905,490,302 is 209601165690.
