Find LCM of 628,405,491,812,700 with Prime Factorization
2 | 628, 405, 491, 812, 700 |
2 | 314, 405, 491, 406, 350 |
5 | 157, 405, 491, 203, 175 |
7 | 157, 81, 491, 203, 35 |
157, 81, 491, 29, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 157 x 81 x 491 x 29 x 5 = 126754154100
Therefore, the lowest common multiple of 628,405,491,812,700 is 126754154100.
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.
628 x 405 x 491 x 812 x 700 = 70982326296000
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.
628 : 1, 2, 4, 157, 314, 628
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
491 : 1, 491
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,405,491,812,700, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
405:3x 3x 3x 3x 5
491:491
812:2x 2x 7x 29
700:2x 2x 5x 5x 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 2x 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 70982326296000/(1x560)
LCM = 70982326296000/560
LCM = 126754154100
Thus, we can understand that the LCM of 628,405,491,812,700 is 126754154100.
