HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 452, 168, 729 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 452, 168, 729 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 452, 168, 729 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 452, 168, 729 is 1.
HCF(452, 168, 729) = 1
HCF of 452, 168, 729 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 452, 168, 729 is 1.
Highest Common Factor of 452,168,729 is 1
Step 1: Since 452 > 168, we apply the division lemma to 452 and 168, to get
452 = 168 x 2 + 116
Step 2: Since the reminder 168 ≠ 0, we apply division lemma to 116 and 168, to get
168 = 116 x 1 + 52
Step 3: We consider the new divisor 116 and the new remainder 52, and apply the division lemma to get
116 = 52 x 2 + 12
We consider the new divisor 52 and the new remainder 12,and apply the division lemma to get
52 = 12 x 4 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 452 and 168 is 4
Notice that 4 = HCF(12,4) = HCF(52,12) = HCF(116,52) = HCF(168,116) = HCF(452,168) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 729 > 4, we apply the division lemma to 729 and 4, to get
729 = 4 x 182 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 729 is 1
Notice that 1 = HCF(4,1) = HCF(729,4) .
