HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 986, 24 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 986, 24 is 2 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 170, 986, 24 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 170, 986, 24 is 2.
HCF(170, 986, 24) = 2
HCF of 170, 986, 24 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 170, 986, 24 is 2.
Highest Common Factor of 170,986,24 is 2
Step 1: Since 986 > 170, we apply the division lemma to 986 and 170, to get
986 = 170 x 5 + 136
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 136 and 170, to get
170 = 136 x 1 + 34
Step 3: We consider the new divisor 136 and the new remainder 34, and apply the division lemma to get
136 = 34 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 34, the HCF of 170 and 986 is 34
Notice that 34 = HCF(136,34) = HCF(170,136) = HCF(986,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 34 > 24, we apply the division lemma to 34 and 24, to get
34 = 24 x 1 + 10
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 10 and 24, to get
24 = 10 x 2 + 4
Step 3: We consider the new divisor 10 and the new remainder 4, and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 34 and 24 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(24,10) = HCF(34,24) .
