HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 138, 332, 429 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 138, 332, 429 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 138, 332, 429 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 138, 332, 429 is 1.
HCF(138, 332, 429) = 1
HCF of 138, 332, 429 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 138, 332, 429 is 1.
Highest Common Factor of 138,332,429 is 1
Step 1: Since 332 > 138, we apply the division lemma to 332 and 138, to get
332 = 138 x 2 + 56
Step 2: Since the reminder 138 ≠ 0, we apply division lemma to 56 and 138, to get
138 = 56 x 2 + 26
Step 3: We consider the new divisor 56 and the new remainder 26, and apply the division lemma to get
56 = 26 x 2 + 4
We consider the new divisor 26 and the new remainder 4,and apply the division lemma to get
26 = 4 x 6 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma 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 138 and 332 is 2
Notice that 2 = HCF(4,2) = HCF(26,4) = HCF(56,26) = HCF(138,56) = HCF(332,138) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 429 > 2, we apply the division lemma to 429 and 2, to get
429 = 2 x 214 + 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 429 is 1
Notice that 1 = HCF(2,1) = HCF(429,2) .
