HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 429, 332, 643 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 76, 429, 332, 643 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 76, 429, 332, 643 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 76, 429, 332, 643 is 1.
HCF(76, 429, 332, 643) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 76, 429, 332, 643 is 1.
Step 1: Since 429 > 76, we apply the division lemma to 429 and 76, to get
429 = 76 x 5 + 49
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 49 and 76, to get
76 = 49 x 1 + 27
Step 3: We consider the new divisor 49 and the new remainder 27, and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 76 and 429 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(76,49) = HCF(429,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 332 > 1, we apply the division lemma to 332 and 1, to get
332 = 1 x 332 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 332 is 1
Notice that 1 = HCF(332,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 643 > 1, we apply the division lemma to 643 and 1, to get
643 = 1 x 643 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 643 is 1
Notice that 1 = HCF(643,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
