HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 729, 64, 541 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 729, 64, 541 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 838, 729, 64, 541 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 838, 729, 64, 541 is 1.
HCF(838, 729, 64, 541) = 1
HCF of 838, 729, 64, 541 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 729, 64, 541 is 1.
Highest Common Factor of 838,729,64,541 is 1
Step 1: Since 838 > 729, we apply the division lemma to 838 and 729, to get
838 = 729 x 1 + 109
Step 2: Since the reminder 729 ≠ 0, we apply division lemma to 109 and 729, to get
729 = 109 x 6 + 75
Step 3: We consider the new divisor 109 and the new remainder 75, and apply the division lemma to get
109 = 75 x 1 + 34
We consider the new divisor 75 and the new remainder 34,and apply the division lemma to get
75 = 34 x 2 + 7
We consider the new divisor 34 and the new remainder 7,and apply the division lemma to get
34 = 7 x 4 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 838 and 729 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(34,7) = HCF(75,34) = HCF(109,75) = HCF(729,109) = HCF(838,729) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get
64 = 1 x 64 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1
Notice that 1 = HCF(64,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 541 > 1, we apply the division lemma to 541 and 1, to get
541 = 1 x 541 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 541 is 1
Notice that 1 = HCF(541,1) .
