HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 872, 70996 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 872, 70996 is 4 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 872, 70996 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 872, 70996 is 4.
HCF(872, 70996) = 4
HCF of 872, 70996 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 872, 70996 is 4.
Highest Common Factor of 872,70996 is 4
Step 1: Since 70996 > 872, we apply the division lemma to 70996 and 872, to get
70996 = 872 x 81 + 364
Step 2: Since the reminder 872 ≠ 0, we apply division lemma to 364 and 872, to get
872 = 364 x 2 + 144
Step 3: We consider the new divisor 364 and the new remainder 144, and apply the division lemma to get
364 = 144 x 2 + 76
We consider the new divisor 144 and the new remainder 76,and apply the division lemma to get
144 = 76 x 1 + 68
We consider the new divisor 76 and the new remainder 68,and apply the division lemma to get
76 = 68 x 1 + 8
We consider the new divisor 68 and the new remainder 8,and apply the division lemma to get
68 = 8 x 8 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 872 and 70996 is 4
Notice that 4 = HCF(8,4) = HCF(68,8) = HCF(76,68) = HCF(144,76) = HCF(364,144) = HCF(872,364) = HCF(70996,872) .
