The LCM of 153,490,765,954 is 3973410.
Find LCM of 153,490,765,954 with Prime Factorization
| 2 | 153, 490, 765, 954 |
| 3 | 153, 245, 765, 477 |
| 3 | 51, 245, 255, 159 |
| 5 | 17, 245, 85, 53 |
| 17 | 17, 49, 17, 53 |
| 1, 49, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 1 x 49 x 1 x 53 = 3973410
Therefore, the lowest common multiple of 153,490,765,954 is 3973410.
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.
153 x 490 x 765 x 954 = 54713855700
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.
153 : 1, 3, 9, 17, 51, 153
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,490,765,954, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
490:2x 5x 7x 7
765:3x 3x 5x 17
954:2x 3x 3x 53
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 3x 3x 3x 5x 17 = 13770
Therefore, the value for common factors is 13770.
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 = 54713855700/(1x13770)
LCM = 54713855700/13770
LCM = 3973410
Thus, we can understand that the LCM of 153,490,765,954 is 3973410.
