इकाई अंक ज्ञात करने के लिए, दी गयी संख्या का इकाई अंक लेते हैं और घात से इसकी चक्रीयता ज्ञात करते हैं।
उदाहरण: 25
∵ इकाई अंक के रूप में 2 को प्रत्येक 4 घात के बाद दोहराया जाता है, 21 = 2, 22 = 4, 23 = 8, 24 = 16, 25 = 32
⇒ 2 की चक्रीयता = 4
25 का इकाई अंक = 21 = 2
उसी प्रकार, 3 की चक्रीयता = 4
गणना:
(1373)36 – (1442)20 का इकाई अंक
⇒ (3)36 – (2)20 का इकाई अंक
⇒ {(3)9 × 4 – (2)5 × 4} का इकाई अंक
⇒ {(3)4 – (2)4} का इकाई अंक
⇒ {81 – 16} का इकाई अंक
⇒ 65 का इकाई अंक
