HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 7604, 2143 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 429, 7604, 2143 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 429, 7604, 2143 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 429, 7604, 2143 is 1.
HCF(429, 7604, 2143) = 1
HCF of 429, 7604, 2143 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 429, 7604, 2143 is 1.
Highest Common Factor of 429,7604,2143 is 1
Step 1: Since 7604 > 429, we apply the division lemma to 7604 and 429, to get
7604 = 429 x 17 + 311
Step 2: Since the reminder 429 ≠ 0, we apply division lemma to 311 and 429, to get
429 = 311 x 1 + 118
Step 3: We consider the new divisor 311 and the new remainder 118, and apply the division lemma to get
311 = 118 x 2 + 75
We consider the new divisor 118 and the new remainder 75,and apply the division lemma to get
118 = 75 x 1 + 43
We consider the new divisor 75 and the new remainder 43,and apply the division lemma to get
75 = 43 x 1 + 32
We consider the new divisor 43 and the new remainder 32,and apply the division lemma to get
43 = 32 x 1 + 11
We consider the new divisor 32 and the new remainder 11,and apply the division lemma to get
32 = 11 x 2 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
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 429 and 7604 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(32,11) = HCF(43,32) = HCF(75,43) = HCF(118,75) = HCF(311,118) = HCF(429,311) = HCF(7604,429) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2143 > 1, we apply the division lemma to 2143 and 1, to get
2143 = 1 x 2143 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2143 is 1
Notice that 1 = HCF(2143,1) .
