HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 119, 128 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 671, 119, 128 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, 119, 128 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, 119, 128 is 1.
HCF(671, 119, 128) = 1
HCF of 671, 119, 128 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, 119, 128 is 1.
Highest Common Factor of 671,119,128 is 1
Step 1: Since 671 > 119, we apply the division lemma to 671 and 119, to get
671 = 119 x 5 + 76
Step 2: Since the reminder 119 ≠ 0, we apply division lemma to 76 and 119, to get
119 = 76 x 1 + 43
Step 3: We consider the new divisor 76 and the new remainder 43, and apply the division lemma to get
76 = 43 x 1 + 33
We consider the new divisor 43 and the new remainder 33,and apply the division lemma to get
43 = 33 x 1 + 10
We consider the new divisor 33 and the new remainder 10,and apply the division lemma to get
33 = 10 x 3 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 119 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(33,10) = HCF(43,33) = HCF(76,43) = HCF(119,76) = HCF(671,119) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 128 > 1, we apply the division lemma to 128 and 1, to get
128 = 1 x 128 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 128 is 1
Notice that 1 = HCF(128,1) .
