- Multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, 54, 60…..

Multiples of 8 are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80…….

Common factors are 24, 48, 72…..

LCM = 24 - Cost of 12 pencils = 48 rupees

Cost of 1 pencil = 48/12 = 4 rupees - Place values of 7 are 70000 and 70.

Difference = 70000 – 70 = 69930 - 6789 rounds off to 6800

4352 rounds off to 4400

Estimated difference = 6800 – 4400 = 2400.
