HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 133, 182 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 133, 182 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 639, 133, 182 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 639, 133, 182 is 1.
HCF(639, 133, 182) = 1
HCF of 639, 133, 182 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 133, 182 is 1.
Highest Common Factor of 639,133,182 is 1
Step 1: Since 639 > 133, we apply the division lemma to 639 and 133, to get
639 = 133 x 4 + 107
Step 2: Since the reminder 133 ≠ 0, we apply division lemma to 107 and 133, to get
133 = 107 x 1 + 26
Step 3: We consider the new divisor 107 and the new remainder 26, and apply the division lemma to get
107 = 26 x 4 + 3
We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get
26 = 3 x 8 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 639 and 133 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(107,26) = HCF(133,107) = HCF(639,133) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 182 > 1, we apply the division lemma to 182 and 1, to get
182 = 1 x 182 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 182 is 1
Notice that 1 = HCF(182,1) .
