Answer:
Given terms: –
am + 1, am + 2, am + 3
Formula used: –
LCM = Least Common Multiple
Means it is the lowest term by which every element must be
divided completely;
am + 1 = am × a
am + 2 = am × a × a
am + 3 = am × a × a × a
⇒ first find the common factors in all terms
Common factor = am × a
Common factor from any 2 terms
= ( am × a) × [(1)(a)(a2)]
= ( am × a) × a[(1)(1)(a)]
⇒ then multiply the remaining factors of terms in common
factor to get the LCM
= ( am × a2)(a)
= ama3
Conclusion: –
The LCM of given terms [am + 1, am + 2, am + 3] is ama3
