The LCM of 98, 145 and 505 is:

Correct option is D

Given:

Number given are 98,145,505

Formula Used:

Prime factorisation

Solution:

Prime factorisation of number are:

98 =$$2 \times 7^{2}$$​​

145 =$$5\times 29$$​​

505 =$$5 \times 101$$​​

For LCM we include maximum number of all factors appearing, hence

LCM =$$2 \times 5 \times 7^{2}\times 29 \times 101$$​​

= 14,35,210
