HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 451, 769, 241 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 451, 769, 241 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 671, 451, 769, 241 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 671, 451, 769, 241 is 1.
HCF(671, 451, 769, 241) = 1
HCF of 671, 451, 769, 241 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 671, 451, 769, 241 is 1.
Highest Common Factor of 671,451,769,241 is 1
Step 1: Since 671 > 451, we apply the division lemma to 671 and 451, to get
671 = 451 x 1 + 220
Step 2: Since the reminder 451 ≠ 0, we apply division lemma to 220 and 451, to get
451 = 220 x 2 + 11
Step 3: We consider the new divisor 220 and the new remainder 11, and apply the division lemma to get
220 = 11 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 671 and 451 is 11
Notice that 11 = HCF(220,11) = HCF(451,220) = HCF(671,451) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 769 > 11, we apply the division lemma to 769 and 11, to get
769 = 11 x 69 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 769 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(769,11) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 241 > 1, we apply the division lemma to 241 and 1, to get
241 = 1 x 241 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 241 is 1
Notice that 1 = HCF(241,1) .
