Question
Determine the $L.C.M$ of the numbers given below: $56, 65, 85$
✓
Answer
$56, 65, 85$
Prime factorization of $56 = 2 \times 2 \times 2 \times 7$
Prime factorization of $65 = 5 \times 13$
Prime factorization of $85 = 5 \times 17$
Therefore, Required $LCM = 2 \times 2 \times 2 \times 5 \times 7 \times 13 \times 17 = 61,880$
