HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 686, 956, 716 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 686, 956, 716 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 686, 956, 716 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 686, 956, 716 is 2.
HCF(686, 956, 716) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 686, 956, 716 is 2.
Step 1: Since 956 > 686, we apply the division lemma to 956 and 686, to get
956 = 686 x 1 + 270
Step 2: Since the reminder 686 ≠ 0, we apply division lemma to 270 and 686, to get
686 = 270 x 2 + 146
Step 3: We consider the new divisor 270 and the new remainder 146, and apply the division lemma to get
270 = 146 x 1 + 124
We consider the new divisor 146 and the new remainder 124,and apply the division lemma to get
146 = 124 x 1 + 22
We consider the new divisor 124 and the new remainder 22,and apply the division lemma to get
124 = 22 x 5 + 14
We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get
22 = 14 x 1 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 686 and 956 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(124,22) = HCF(146,124) = HCF(270,146) = HCF(686,270) = HCF(956,686) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 716 > 2, we apply the division lemma to 716 and 2, to get
716 = 2 x 358 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 716 is 2
Notice that 2 = HCF(716,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
