HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 237, 701 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 237, 701 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 685, 237, 701 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 685, 237, 701 is 1.
HCF(685, 237, 701) = 1
HCF of 685, 237, 701 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 685, 237, 701 is 1.
Highest Common Factor of 685,237,701 is 1
Step 1: Since 685 > 237, we apply the division lemma to 685 and 237, to get
685 = 237 x 2 + 211
Step 2: Since the reminder 237 ≠ 0, we apply division lemma to 211 and 237, to get
237 = 211 x 1 + 26
Step 3: We consider the new divisor 211 and the new remainder 26, and apply the division lemma to get
211 = 26 x 8 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 685 and 237 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(211,26) = HCF(237,211) = HCF(685,237) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 701 > 1, we apply the division lemma to 701 and 1, to get
701 = 1 x 701 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 701 is 1
Notice that 1 = HCF(701,1) .
