Given numbers are 649,390,737,962
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,390,737,962 is 627459690.
Find LCM of 649,390,737,962 with Prime Factorization
| 2 | 649, 390, 737, 962 |
| 11 | 649, 195, 737, 481 |
| 13 | 59, 195, 67, 481 |
| 59, 15, 67, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 59 x 15 x 67 x 37 = 627459690
Therefore, the lowest common multiple of 649,390,737,962 is 627459690.
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.
649 x 390 x 737 x 962 = 179453471340
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.
649 : 1, 11, 59, 649
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
737 : 1, 11, 67, 737
962 : 1, 2, 13, 26, 37, 74, 481, 962
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,390,737,962, is 1.
Now, the common factors can be found like this.
649:11x 59
390:2x 3x 5x 13
737:11x 67
962:2x 13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 179453471340/(1x286)
LCM = 179453471340/286
LCM = 627459690
Thus, we can understand that the LCM of 649,390,737,962 is 627459690.
