Given numbers are 620,352,897,628,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,352,897,628,658 is 2527914348960.
Find LCM of 620,352,897,628,658 with Prime Factorization
| 2 | 620, 352, 897, 628, 658 |
| 2 | 310, 176, 897, 314, 329 |
| 155, 88, 897, 157, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 155 x 88 x 897 x 157 x 329 = 2527914348960
Therefore, the lowest common multiple of 620,352,897,628,658 is 2527914348960.
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.
620 x 352 x 897 x 628 x 658 = 80893259166720
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
897 : 1, 3, 13, 23, 39, 69, 299, 897
628 : 1, 2, 4, 157, 314, 628
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,352,897,628,658, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
352:2x 2x 2x 2x 2x 11
897:3x 13x 23
628:2x 2x 157
658:2x 7x 47
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 2 = 32
Therefore, the value for common factors is 32.
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 = 80893259166720/(1x32)
LCM = 80893259166720/32
LCM = 2527914348960
Thus, we can understand that the LCM of 620,352,897,628,658 is 2527914348960.
