UCT and ICM of 510 and 92 and also verify it.​

Answer 1

first we take HCF of 6- 2×3

HCF of 72-2×2×2×3×3

HCF of 120-2×2×2×3×5

Now HCF is 2×3

=6

Now for LCM 2×2×2×3××3×5

Answer 2

Answer:

HCF = 6 .

LCM = 360.

Step-by-step explanation:

Given no.are 6 , 72 and 120.

these no. factors are -

6 = 2×3

72= 36×2

= 6×6×2

= 2×32×3×2

= (2×3)² ×2

= 2³×3²

120 =12×10

=3×4×2×5

=3×2×2×2×5

=3×2²×5

HCF = 2¹×3¹×5⁰

=2×3

=6

LCM = 2³×3²×5

=8×9×5

=40×9

=360
