Find LCM of 664,160,695,398,749 with Prime Factorization
| 2 | 664, 160, 695, 398, 749 |
| 2 | 332, 80, 695, 199, 749 |
| 2 | 166, 40, 695, 199, 749 |
| 5 | 83, 20, 695, 199, 749 |
| 83, 4, 139, 199, 749 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 83 x 4 x 139 x 199 x 749 = 275136221920
Therefore, the lowest common multiple of 664,160,695,398,749 is 275136221920.
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.
664 x 160 x 695 x 398 x 749 = 22010897753600
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.
664 : 1, 2, 4, 8, 83, 166, 332, 664
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
695 : 1, 5, 139, 695
398 : 1, 2, 199, 398
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,160,695,398,749, is 1.
Now, the common factors can be found like this.
664:2x 2x 2x 83
160:2x 2x 2x 2x 2x 5
695:5x 139
398:2x 199
749:7x 107
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 5 = 80
Therefore, the value for common factors is 80.
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 = 22010897753600/(1x80)
LCM = 22010897753600/80
LCM = 275136221920
Thus, we can understand that the LCM of 664,160,695,398,749 is 275136221920.
