Given numbers are 345,854,784,577,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 345,854,784,577,947 is 9015520078320.
Find LCM of 345,854,784,577,947 with Prime Factorization
2 | 345, 854, 784, 577, 947 |
7 | 345, 427, 392, 577, 947 |
345, 61, 56, 577, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 345 x 61 x 56 x 577 x 947 = 9015520078320
Therefore, the lowest common multiple of 345,854,784,577,947 is 9015520078320.
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.
345 x 854 x 784 x 577 x 947 = 126217281096480
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.
345 : 1, 3, 5, 15, 23, 69, 115, 345
854 : 1, 2, 7, 14, 61, 122, 427, 854
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
577 : 1, 577
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 345,854,784,577,947, is 1.
Now, the common factors can be found like this.
345:3x 5x 23
854:2x 7x 61
784:2x 2x 2x 2x 7x 7
577:577
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 126217281096480/(1x14)
LCM = 126217281096480/14
LCM = 9015520078320
Thus, we can understand that the LCM of 345,854,784,577,947 is 9015520078320.
