Explain with steps ya!​

Answer 1

Step-by-step explanation:

The least number divisible by all the number from 1 to 10 will be the L.C.M of following number,

1=1

1=12=2×1

1=12=2×13=3×1

1=12=2×13=3×14=2×2

1=12=2×13=3×14=2×25=5×1

1=12=2×13=3×14=2×25=5×16=2×3

1=12=2×13=3×14=2×25=5×16=2×37=7×1

1=12=2×13=3×14=2×25=5×16=2×37=7×18=2×2×2

1=12=2×13=3×14=2×25=5×16=2×37=7×18=2×2×29=3×3

1=12=2×13=3×14=2×25=5×16=2×37=7×18=2×2×29=3×310=2×5

So, the L.C.M. of these number is 1×2×2×2×3×3×5×7=2520

Hence, the least number divisible by all the numbers from 1 to 10 is 2520
