Given numbers are 719,788,820,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 719,788,820,697 is 1974503420.
Find LCM of 719,788,820,697 with Prime Factorization
2 | 719, 788, 820, 697 |
2 | 719, 394, 410, 697 |
41 | 719, 197, 205, 697 |
719, 197, 5, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 719 x 197 x 5 x 17 = 1974503420
Therefore, the lowest common multiple of 719,788,820,697 is 1974503420.
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.
719 x 788 x 820 x 697 = 323818560880
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.
719 : 1, 719
788 : 1, 2, 4, 197, 394, 788
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 719,788,820,697, is 1.
Now, the common factors can be found like this.
719:719
788:2x 2x 197
820:2x 2x 5x 41
697:17x 41
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 41 = 164
Therefore, the value for common factors is 164.
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 = 323818560880/(1x164)
LCM = 323818560880/164
LCM = 1974503420
Thus, we can understand that the LCM of 719,788,820,697 is 1974503420.
