Given numbers are 657,989,407,798
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,989,407,798 is 70345724526.
Find LCM of 657,989,407,798 with Prime Factorization
| 3 | 657, 989, 407, 798 |
| 219, 989, 407, 266 |
Multiply the prime numbers at the bottom and the left side.
3 x 219 x 989 x 407 x 266 = 70345724526
Therefore, the lowest common multiple of 657,989,407,798 is 70345724526.
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.
657 x 989 x 407 x 798 = 211037173578
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.
657 : 1, 3, 9, 73, 219, 657
989 : 1, 23, 43, 989
407 : 1, 11, 37, 407
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,989,407,798, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
989:23x 43
407:11x 37
798:2x 3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 211037173578/(1x3)
LCM = 211037173578/3
LCM = 70345724526
Thus, we can understand that the LCM of 657,989,407,798 is 70345724526.
