Given numbers are 661,563,151,784,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,563,151,784,755 is 220278884560.
Find LCM of 661,563,151,784,755 with Prime Factorization
151 | 661, 563, 151, 784, 755 |
661, 563, 1, 784, 5 |
Multiply the prime numbers at the bottom and the left side.
151 x 661 x 563 x 1 x 784 x 5 = 220278884560
Therefore, the lowest common multiple of 661,563,151,784,755 is 220278884560.
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.
661 x 563 x 151 x 784 x 755 = 33262111568560
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.
661 : 1, 661
563 : 1, 563
151 : 1, 151
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,563,151,784,755, is 1.
Now, the common factors can be found like this.
661:661
563:563
151:151
784:2x 2x 2x 2x 7x 7
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
151 = 151
Therefore, the value for common factors is 151.
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 = 33262111568560/(1x151)
LCM = 33262111568560/151
LCM = 220278884560
Thus, we can understand that the LCM of 661,563,151,784,755 is 220278884560.
