Given numbers are 245,142,121,788,349

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 245,142,121,788,349 is 578843882540.

Find LCM of 245,142,121,788,349 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 245 x 71 x 121 x 394 x 349 = 578843882540

Therefore, the lowest common multiple of 245,142,121,788,349 is 578843882540.

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.

245 x 142 x 121 x 788 x 349 = 1157687765080

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.

245 : 1, 5, 7, 35, 49, 245

142 : 1, 2, 71, 142

121 : 1, 11, 121

788 : 1, 2, 4, 197, 394, 788

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 245,142,121,788,349, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

142:2x 71

121:11x 11

788:2x 2x 197

349:349

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 1157687765080/(1x2)

LCM = 1157687765080/2

LCM = 578843882540

Thus, we can understand that the LCM of 245,142,121,788,349 is 578843882540.
