HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 934, 688, 20, 251 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 934, 688, 20, 251 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 934, 688, 20, 251 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 934, 688, 20, 251 is 1.
HCF(934, 688, 20, 251) = 1
HCF of 934, 688, 20, 251 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 934, 688, 20, 251 is 1.
Highest Common Factor of 934,688,20,251 is 1
Step 1: Since 934 > 688, we apply the division lemma to 934 and 688, to get
934 = 688 x 1 + 246
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 246 and 688, to get
688 = 246 x 2 + 196
Step 3: We consider the new divisor 246 and the new remainder 196, and apply the division lemma to get
246 = 196 x 1 + 50
We consider the new divisor 196 and the new remainder 50,and apply the division lemma to get
196 = 50 x 3 + 46
We consider the new divisor 50 and the new remainder 46,and apply the division lemma to get
50 = 46 x 1 + 4
We consider the new divisor 46 and the new remainder 4,and apply the division lemma to get
46 = 4 x 11 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 934 and 688 is 2
Notice that 2 = HCF(4,2) = HCF(46,4) = HCF(50,46) = HCF(196,50) = HCF(246,196) = HCF(688,246) = HCF(934,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 20 > 2, we apply the division lemma to 20 and 2, to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 20 is 2
Notice that 2 = HCF(20,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 251 > 2, we apply the division lemma to 251 and 2, to get
251 = 2 x 125 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 251 is 1
Notice that 1 = HCF(2,1) = HCF(251,2) .
