Given numbers are 749,770,147,453
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,770,147,453 is 261258690.
Find LCM of 749,770,147,453 with Prime Factorization
| 3 | 749, 770, 147, 453 |
| 7 | 749, 770, 49, 151 |
| 107, 110, 7, 151 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 107 x 110 x 7 x 151 = 261258690
Therefore, the lowest common multiple of 749,770,147,453 is 261258690.
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.
749 x 770 x 147 x 453 = 38405027430
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.
749 : 1, 7, 107, 749
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
147 : 1, 3, 7, 21, 49, 147
453 : 1, 3, 151, 453
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,770,147,453, is 1.
Now, the common factors can be found like this.
749:7x 107
770:2x 5x 7x 11
147:3x 7x 7
453:3x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 38405027430/(1x147)
LCM = 38405027430/147
LCM = 261258690
Thus, we can understand that the LCM of 749,770,147,453 is 261258690.
