Calculate the LCM of 751,459,128,659,978

Given numbers are 751,459,128,659,978

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

The LCM of 751,459,128,659,978 is 4739533651584.

Find LCM of 751,459,128,659,978 with Prime Factorization


2 751, 459, 128, 659, 978
3 751, 459, 64, 659, 489
751, 153, 64, 659, 163

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

2 x 3 x 751 x 153 x 64 x 659 x 163 = 4739533651584

Therefore, the lowest common multiple of 751,459,128,659,978 is 4739533651584.

LCM Formula to Find Lowest Common Multiple of 751,459,128,659,978

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.

751 x 459 x 128 x 659 x 978 = 28437201909504

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.

751 : 1, 751

459 : 1, 3, 9, 17, 27, 51, 153, 459

128 : 1, 2, 4, 8, 16, 32, 64, 128

659 : 1, 659

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,459,128,659,978, is 1.

Now, the common factors can be found like this.

751:751

459:3x 3x 3x 17

128:2x 2x 2x 2x 2x 2x 2

659:659

978:2x 3x 163

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 = 28437201909504/(1x6)

LCM = 28437201909504/6

LCM = 4739533651584

Thus, we can understand that the LCM of 751,459,128,659,978 is 4739533651584.
