Given numbers are 144,478,160,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 144,478,160,770 is 26500320.
Find LCM of 144,478,160,770 with Prime Factorization
2 | 144, 478, 160, 770 |
2 | 72, 239, 80, 385 |
2 | 36, 239, 40, 385 |
2 | 18, 239, 20, 385 |
5 | 9, 239, 10, 385 |
9, 239, 2, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 9 x 239 x 2 x 77 = 26500320
Therefore, the lowest common multiple of 144,478,160,770 is 26500320.
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.
144 x 478 x 160 x 770 = 8480102400
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.
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
478 : 1, 2, 239, 478
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 144,478,160,770, is 2.
Now, the common factors can be found like this.
144:2x 2x 2x 2x 3x 3
478:2x 239
160:2x 2x 2x 2x 2x 5
770:2x 5x 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 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 8480102400/(2x160)
LCM = 8480102400/320
LCM = 26500320
Thus, we can understand that the LCM of 144,478,160,770 is 26500320.
