Given numbers are 273,221,960,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 273,221,960,971 is 1442051520.
Find LCM of 273,221,960,971 with Prime Factorization
3 | 273, 221, 960, 971 |
13 | 91, 221, 320, 971 |
7, 17, 320, 971 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 7 x 17 x 320 x 971 = 1442051520
Therefore, the lowest common multiple of 273,221,960,971 is 1442051520.
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.
273 x 221 x 960 x 971 = 56240009280
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
221 : 1, 13, 17, 221
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,221,960,971, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
221:13x 17
960:2x 2x 2x 2x 2x 2x 3x 5
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 56240009280/(1x39)
LCM = 56240009280/39
LCM = 1442051520
Thus, we can understand that the LCM of 273,221,960,971 is 1442051520.
