Given numbers are 676,680,221,126
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,680,221,126 is 7239960.
Find LCM of 676,680,221,126 with Prime Factorization
2 | 676, 680, 221, 126 |
2 | 338, 340, 221, 63 |
13 | 169, 170, 221, 63 |
17 | 13, 170, 17, 63 |
13, 10, 1, 63 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 13 x 10 x 1 x 63 = 7239960
Therefore, the lowest common multiple of 676,680,221,126 is 7239960.
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.
676 x 680 x 221 x 126 = 12800249280
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
221 : 1, 13, 17, 221
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,680,221,126, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
680:2x 2x 2x 5x 17
221:13x 17
126:2x 3x 3x 7
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 13x 17 = 1768
Therefore, the value for common factors is 1768.
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 = 12800249280/(1x1768)
LCM = 12800249280/1768
LCM = 7239960
Thus, we can understand that the LCM of 676,680,221,126 is 7239960.
