Given numbers are 426,697,172,772,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,697,172,772,946 is 54211424916.
Find LCM of 426,697,172,772,946 with Prime Factorization
| 2 | 426, 697, 172, 772, 946 |
| 2 | 213, 697, 86, 386, 473 |
| 43 | 213, 697, 43, 193, 473 |
| 213, 697, 1, 193, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 213 x 697 x 1 x 193 x 11 = 54211424916
Therefore, the lowest common multiple of 426,697,172,772,946 is 54211424916.
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.
426 x 697 x 172 x 772 x 946 = 37297460342208
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
697 : 1, 17, 41, 697
172 : 1, 2, 4, 43, 86, 172
772 : 1, 2, 4, 193, 386, 772
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,697,172,772,946, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
697:17x 41
172:2x 2x 43
772:2x 2x 193
946:2x 11x 43
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 43 = 688
Therefore, the value for common factors is 688.
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 = 37297460342208/(1x688)
LCM = 37297460342208/688
LCM = 54211424916
Thus, we can understand that the LCM of 426,697,172,772,946 is 54211424916.
