Given numbers are 157,221,248,978,777

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

The LCM of 157,221,248,978,777 is 1089813617256.

Find LCM of 157,221,248,978,777 with Prime Factorization

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

2 x 3 x 157 x 221 x 124 x 163 x 259 = 1089813617256

Therefore, the lowest common multiple of 157,221,248,978,777 is 1089813617256.

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.

157 x 221 x 248 x 978 x 777 = 6538881703536

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.

157 : 1, 157

221 : 1, 13, 17, 221

248 : 1, 2, 4, 8, 31, 62, 124, 248

978 : 1, 2, 3, 6, 163, 326, 489, 978

777 : 1, 3, 7, 21, 37, 111, 259, 777

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,221,248,978,777, is 1.

Now, the common factors can be found like this.

157:157

221:13x 17

248:2x 2x 2x 31

978:2x 3x 163

777:3x 7x 37

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 6538881703536/(1x6)

LCM = 6538881703536/6

LCM = 1089813617256

Thus, we can understand that the LCM of 157,221,248,978,777 is 1089813617256.
