Given numbers are 278,253,480,931,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,253,480,931,969 is 267162292320.
Find LCM of 278,253,480,931,969 with Prime Factorization
| 2 | 278, 253, 480, 931, 969 |
| 3 | 139, 253, 240, 931, 969 |
| 19 | 139, 253, 80, 931, 323 |
| 139, 253, 80, 49, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 139 x 253 x 80 x 49 x 17 = 267162292320
Therefore, the lowest common multiple of 278,253,480,931,969 is 267162292320.
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.
278 x 253 x 480 x 931 x 969 = 30456501324480
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.
278 : 1, 2, 139, 278
253 : 1, 11, 23, 253
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
931 : 1, 7, 19, 49, 133, 931
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,253,480,931,969, is 1.
Now, the common factors can be found like this.
278:2x 139
253:11x 23
480:2x 2x 2x 2x 2x 3x 5
931:7x 7x 19
969:3x 17x 19
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 19 = 114
Therefore, the value for common factors is 114.
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 = 30456501324480/(1x114)
LCM = 30456501324480/114
LCM = 267162292320
Thus, we can understand that the LCM of 278,253,480,931,969 is 267162292320.
