HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 835, 726, 685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 835, 726, 685 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 835, 726, 685 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 835, 726, 685 is 1.
HCF(835, 726, 685) = 1
HCF of 835, 726, 685 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 835, 726, 685 is 1.
Highest Common Factor of 835,726,685 is 1
Step 1: Since 835 > 726, we apply the division lemma to 835 and 726, to get
835 = 726 x 1 + 109
Step 2: Since the reminder 726 ≠ 0, we apply division lemma to 109 and 726, to get
726 = 109 x 6 + 72
Step 3: We consider the new divisor 109 and the new remainder 72, and apply the division lemma to get
109 = 72 x 1 + 37
We consider the new divisor 72 and the new remainder 37,and apply the division lemma to get
72 = 37 x 1 + 35
We consider the new divisor 37 and the new remainder 35,and apply the division lemma to get
37 = 35 x 1 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 835 and 726 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(37,35) = HCF(72,37) = HCF(109,72) = HCF(726,109) = HCF(835,726) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 685 > 1, we apply the division lemma to 685 and 1, to get
685 = 1 x 685 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 685 is 1
Notice that 1 = HCF(685,1) .
