HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 708, 961 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 708, 961 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 708, 961 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 708, 961 is 1.
HCF(708, 961) = 1
HCF of 708, 961 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 708, 961 is 1.
Highest Common Factor of 708,961 is 1
Step 1: Since 961 > 708, we apply the division lemma to 961 and 708, to get
961 = 708 x 1 + 253
Step 2: Since the reminder 708 ≠ 0, we apply division lemma to 253 and 708, to get
708 = 253 x 2 + 202
Step 3: We consider the new divisor 253 and the new remainder 202, and apply the division lemma to get
253 = 202 x 1 + 51
We consider the new divisor 202 and the new remainder 51,and apply the division lemma to get
202 = 51 x 3 + 49
We consider the new divisor 51 and the new remainder 49,and apply the division lemma to get
51 = 49 x 1 + 2
We consider the new divisor 49 and the new remainder 2,and apply the division lemma to get
49 = 2 x 24 + 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 708 and 961 is 1
Notice that 1 = HCF(2,1) = HCF(49,2) = HCF(51,49) = HCF(202,51) = HCF(253,202) = HCF(708,253) = HCF(961,708) .
