HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 856, 986, 872 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 856, 986, 872 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 856, 986, 872 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 856, 986, 872 is 2.
HCF(856, 986, 872) = 2
HCF of 856, 986, 872 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 856, 986, 872 is 2.
Highest Common Factor of 856,986,872 is 2
Step 1: Since 986 > 856, we apply the division lemma to 986 and 856, to get
986 = 856 x 1 + 130
Step 2: Since the reminder 856 ≠ 0, we apply division lemma to 130 and 856, to get
856 = 130 x 6 + 76
Step 3: We consider the new divisor 130 and the new remainder 76, and apply the division lemma to get
130 = 76 x 1 + 54
We consider the new divisor 76 and the new remainder 54,and apply the division lemma to get
76 = 54 x 1 + 22
We consider the new divisor 54 and the new remainder 22,and apply the division lemma to get
54 = 22 x 2 + 10
We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get
22 = 10 x 2 + 2
We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 856 and 986 is 2
Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(54,22) = HCF(76,54) = HCF(130,76) = HCF(856,130) = HCF(986,856) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 872 > 2, we apply the division lemma to 872 and 2, to get
872 = 2 x 436 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 872 is 2
Notice that 2 = HCF(872,2) .
