लघुत्तम समापवर्त्य (L.C.M)

परिभाषा

LCM वह सबसे छोटी संख्या है जो दी गई सभी संख्याओं से पूर्णतः विभाजित होती है।

अभाज्य गुणनखंड विधि

उदाहरण 1: 20, 66, 128 का LCM ज्ञात करें

20 = 2 × 2 × 5
66 = 2 × 3 × 11
128 = 2 × 2 × 2 × 2 × 2 × 2 × 2

सभी अभाज्य संख्याओं की उच्चतम घात लें:

LCM = 2⁷ × 3 × 5 × 11 = 42240

उदाहरण 2: 78, 128, 196 का HCF ज्ञात करें

अभाज्य संख्याएँ एवं पूर्ण संख्याएँ

गुणनखंड (Factor)

गुणनखंड वह संख्या है जो किसी दूसरी संख्या को पूर्णतः विभाजित करती है।

उदाहरण:

24, 72, 100 के गुणनखंड निकालें:

24 = 2 × 2 × 2 × 3
72 = 2 × 2 × 2 × 3 × 3
100 = 2 × 2 × 5 × 5

संख्याएँ 2, 3, 5 गुणनखंड कहलाती हैं।

अभाज्य गुणनखंड

अभाज्य गुणनखंड वह अभाज्य संख्या है जो किसी संख्या को पूर्णतः विभाजित करती है।

उदाहरण:

57 = 3 × 19

संख्याएँ 3 और 19 अभाज्य गुणनखंड हैं।
