HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 174, 223, 42, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 174, 223, 42, 681 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 174, 223, 42, 681 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 174, 223, 42, 681 is 1.
HCF(174, 223, 42, 681) = 1
HCF of 174, 223, 42, 681 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 174, 223, 42, 681 is 1.
Highest Common Factor of 174,223,42,681 is 1
Step 1: Since 223 > 174, we apply the division lemma to 223 and 174, to get
223 = 174 x 1 + 49
Step 2: Since the reminder 174 ≠ 0, we apply division lemma to 49 and 174, to get
174 = 49 x 3 + 27
Step 3: We consider the new divisor 49 and the new remainder 27, and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 174 and 223 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(174,49) = HCF(223,174) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 42 > 1, we apply the division lemma to 42 and 1, to get
42 = 1 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 42 is 1
Notice that 1 = HCF(42,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get
681 = 1 x 681 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1
Notice that 1 = HCF(681,1) .
