Given numbers are 724,916,142,124,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,916,142,124,620 is 1824584980.
Find LCM of 724,916,142,124,620 with Prime Factorization
2 | 724, 916, 142, 124, 620 |
2 | 362, 458, 71, 62, 310 |
31 | 181, 229, 71, 31, 155 |
181, 229, 71, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 31 x 181 x 229 x 71 x 1 x 5 = 1824584980
Therefore, the lowest common multiple of 724,916,142,124,620 is 1824584980.
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.
724 x 916 x 142 x 124 x 620 = 7239953200640
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.
724 : 1, 2, 4, 181, 362, 724
916 : 1, 2, 4, 229, 458, 916
142 : 1, 2, 71, 142
124 : 1, 2, 4, 31, 62, 124
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,916,142,124,620, is 2.
Now, the common factors can be found like this.
724:2x 2x 181
916:2x 2x 229
142:2x 71
124:2x 2x 31
620:2x 2x 5x 31
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 2x 2x 31 = 1984
Therefore, the value for common factors is 1984.
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 = 7239953200640/(2x1984)
LCM = 7239953200640/3968
LCM = 1824584980
Thus, we can understand that the LCM of 724,916,142,124,620 is 1824584980.
