Given numbers are 420,803,242,126,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,803,242,126,274 is 1524752460.
Find LCM of 420,803,242,126,274 with Prime Factorization
| 2 | 420, 803, 242, 126, 274 |
| 3 | 210, 803, 121, 63, 137 |
| 7 | 70, 803, 121, 21, 137 |
| 11 | 10, 803, 121, 3, 137 |
| 10, 73, 11, 3, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 10 x 73 x 11 x 3 x 137 = 1524752460
Therefore, the lowest common multiple of 420,803,242,126,274 is 1524752460.
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.
420 x 803 x 242 x 126 x 274 = 2817742546080
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.
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
803 : 1, 11, 73, 803
242 : 1, 2, 11, 22, 121, 242
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,803,242,126,274, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
803:11x 73
242:2x 11x 11
126:2x 3x 3x 7
274:2x 137
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 3x 7x 11 = 1848
Therefore, the value for common factors is 1848.
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 = 2817742546080/(1x1848)
LCM = 2817742546080/1848
LCM = 1524752460
Thus, we can understand that the LCM of 420,803,242,126,274 is 1524752460.
