HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 961, 268, 24 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 961, 268, 24 is 1 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 961, 268, 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 961, 268, 24 is 1.
HCF(961, 268, 24) = 1
HCF of 961, 268, 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 961, 268, 24 is 1.
Highest Common Factor of 961,268,24 is 1
Step 1: Since 961 > 268, we apply the division lemma to 961 and 268, to get
961 = 268 x 3 + 157
Step 2: Since the reminder 268 ≠ 0, we apply division lemma to 157 and 268, to get
268 = 157 x 1 + 111
Step 3: We consider the new divisor 157 and the new remainder 111, and apply the division lemma to get
157 = 111 x 1 + 46
We consider the new divisor 111 and the new remainder 46,and apply the division lemma to get
111 = 46 x 2 + 19
We consider the new divisor 46 and the new remainder 19,and apply the division lemma to get
46 = 19 x 2 + 8
We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get
19 = 8 x 2 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 961 and 268 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(46,19) = HCF(111,46) = HCF(157,111) = HCF(268,157) = HCF(961,268) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get
24 = 1 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1
Notice that 1 = HCF(24,1) .
