Given numbers are 314,371,420,392,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 314,371,420,392,971 is 47508583080.
Find LCM of 314,371,420,392,971 with Prime Factorization
| 2 | 314, 371, 420, 392, 971 |
| 2 | 157, 371, 210, 196, 971 |
| 7 | 157, 371, 105, 98, 971 |
| 157, 53, 15, 14, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 157 x 53 x 15 x 14 x 971 = 47508583080
Therefore, the lowest common multiple of 314,371,420,392,971 is 47508583080.
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.
314 x 371 x 420 x 392 x 971 = 18623364567360
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.
314 : 1, 2, 157, 314
371 : 1, 7, 53, 371
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 314,371,420,392,971, is 1.
Now, the common factors can be found like this.
314:2x 157
371:7x 53
420:2x 2x 3x 5x 7
392:2x 2x 2x 7x 7
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.
2x 2x 2x 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 18623364567360/(1x392)
LCM = 18623364567360/392
LCM = 47508583080
Thus, we can understand that the LCM of 314,371,420,392,971 is 47508583080.
