Given numbers are 722,513,989,764,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,513,989,764,618 is 758573803836.
Find LCM of 722,513,989,764,618 with Prime Factorization
| 2 | 722, 513, 989, 764, 618 |
| 3 | 361, 513, 989, 382, 309 |
| 19 | 361, 171, 989, 382, 103 |
| 19, 9, 989, 382, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 19 x 9 x 989 x 382 x 103 = 758573803836
Therefore, the lowest common multiple of 722,513,989,764,618 is 758573803836.
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.
722 x 513 x 989 x 764 x 618 = 172954827274608
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.
722 : 1, 2, 19, 38, 361, 722
513 : 1, 3, 9, 19, 27, 57, 171, 513
989 : 1, 23, 43, 989
764 : 1, 2, 4, 191, 382, 764
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,513,989,764,618, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
513:3x 3x 3x 19
989:23x 43
764:2x 2x 191
618:2x 3x 103
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 172954827274608/(1x228)
LCM = 172954827274608/228
LCM = 758573803836
Thus, we can understand that the LCM of 722,513,989,764,618 is 758573803836.
