Given numbers are 715,578,539,697
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,578,539,697 is 830259430.
Find LCM of 715,578,539,697 with Prime Factorization
11 | 715, 578, 539, 697 |
17 | 65, 578, 49, 697 |
65, 34, 49, 41 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 65 x 34 x 49 x 41 = 830259430
Therefore, the lowest common multiple of 715,578,539,697 is 830259430.
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.
715 x 578 x 539 x 697 = 155258513410
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
578 : 1, 2, 17, 34, 289, 578
539 : 1, 7, 11, 49, 77, 539
697 : 1, 17, 41, 697
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,578,539,697, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
578:2x 17x 17
539:7x 7x 11
697:17x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 155258513410/(1x187)
LCM = 155258513410/187
LCM = 830259430
Thus, we can understand that the LCM of 715,578,539,697 is 830259430.
