Given numbers are 697,818,665,973,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,818,665,973,779 is 52701445510.
Find LCM of 697,818,665,973,779 with Prime Factorization
| 7 | 697, 818, 665, 973, 779 |
| 19 | 697, 818, 95, 139, 779 |
| 41 | 697, 818, 5, 139, 41 |
| 17, 818, 5, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
7 x 19 x 41 x 17 x 818 x 5 x 139 x 1 = 52701445510
Therefore, the lowest common multiple of 697,818,665,973,779 is 52701445510.
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.
697 x 818 x 665 x 973 x 779 = 287380982366030
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.
697 : 1, 17, 41, 697
818 : 1, 2, 409, 818
665 : 1, 5, 7, 19, 35, 95, 133, 665
973 : 1, 7, 139, 973
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,818,665,973,779, is 1.
Now, the common factors can be found like this.
697:17x 41
818:2x 409
665:5x 7x 19
973:7x 139
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 19x 41 = 5453
Therefore, the value for common factors is 5453.
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 = 287380982366030/(1x5453)
LCM = 287380982366030/5453
LCM = 52701445510
Thus, we can understand that the LCM of 697,818,665,973,779 is 52701445510.
