Question

84 , 105 , 168 find HCF with solution

Answer 1

Step-by-step explanation:

we know that we have to find the hcf of 84 and 105

factors of 84 =1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84

factors of 105 =1, 3, 5, 7, 15, 21, 35, 105

we find 7 is the highest factor hence HCF of 84 and 105 is 7.

Answer 2

Answer:

step 1 - take the hcf of 84,105,168

step 2 - find the common in all these of your answer

step 3 - you will find 3 and 7 now
