Question

lcm and hcf of 25*54*72*136 and 23*56*7*173
​

Answer 1

LCM= 68,14,80,800

Step-by-step explanation: We have to only write the number in the multiple of their prime factors

25= 5 x 5

37= 1 x 37

52= 2 x 2 x 13

7=1x7

=> 25 x 37 x 52 x 7= 2 x 2 x 5x5x7x

13 x 37

23= 1 x 23

32= 2 x 2 x 2 x 2 x 2

56= 2 x 2 x 2 x 7

=> 23 x 32 x 56 x 11= 2 x 2 x 2 x 2 x 2 x 7 x 11 x 23

HCF = 2 x 2 x 7= 28

LCM= 2 x 2 x 2 x 2 x 2 x 5 x 5 x 7 x 11 x 13 x 23 x 37 = 68,14,80,800

Answer 2

Answer:

Step-by-step explanation:

=> 25 x 54 x 72 x 136= 2^7 x 3^5 x 5^2 x 17

=> 23 x 32 x 56 x 173= 2^3 x 7^2 x 23 x 173

HCF=2^3=8

LCM=2^3 x 3^5 x 5^2 x 17 x 7^2 x 23 x 173=338220570600
