HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 668, 148, 922, 271 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 668, 148, 922, 271 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 668, 148, 922, 271 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 668, 148, 922, 271 is 1.
HCF(668, 148, 922, 271) = 1
HCF of 668, 148, 922, 271 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 668, 148, 922, 271 is 1.
Highest Common Factor of 668,148,922,271 is 1
Step 1: Since 668 > 148, we apply the division lemma to 668 and 148, to get
668 = 148 x 4 + 76
Step 2: Since the reminder 148 ≠ 0, we apply division lemma to 76 and 148, to get
148 = 76 x 1 + 72
Step 3: We consider the new divisor 76 and the new remainder 72, and apply the division lemma to get
76 = 72 x 1 + 4
We consider the new divisor 72 and the new remainder 4, and apply the division lemma to get
72 = 4 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 668 and 148 is 4
Notice that 4 = HCF(72,4) = HCF(76,72) = HCF(148,76) = HCF(668,148) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 922 > 4, we apply the division lemma to 922 and 4, to get
922 = 4 x 230 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, 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 4 and 922 is 2
Notice that 2 = HCF(4,2) = HCF(922,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 271 > 2, we apply the division lemma to 271 and 2, to get
271 = 2 x 135 + 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 271 is 1
Notice that 1 = HCF(2,1) = HCF(271,2) .
