Given numbers are 739,830,749,705,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 739,830,749,705,770 is 712551315630.
Find LCM of 739,830,749,705,770 with Prime Factorization
| 2 | 739, 830, 749, 705, 770 |
| 5 | 739, 415, 749, 705, 385 |
| 7 | 739, 83, 749, 141, 77 |
| 739, 83, 107, 141, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 739 x 83 x 107 x 141 x 11 = 712551315630
Therefore, the lowest common multiple of 739,830,749,705,770 is 712551315630.
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.
739 x 830 x 749 x 705 x 770 = 249392960470500
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.
739 : 1, 739
830 : 1, 2, 5, 10, 83, 166, 415, 830
749 : 1, 7, 107, 749
705 : 1, 3, 5, 15, 47, 141, 235, 705
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 739,830,749,705,770, is 1.
Now, the common factors can be found like this.
739:739
830:2x 5x 83
749:7x 107
705:3x 5x 47
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 249392960470500/(1x350)
LCM = 249392960470500/350
LCM = 712551315630
Thus, we can understand that the LCM of 739,830,749,705,770 is 712551315630.
