HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 443, 722, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 443, 722, 64 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 170, 443, 722, 64 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 170, 443, 722, 64 is 1.
HCF(170, 443, 722, 64) = 1
HCF of 170, 443, 722, 64 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 170, 443, 722, 64 is 1.
Highest Common Factor of 170,443,722,64 is 1
Step 1: Since 443 > 170, we apply the division lemma to 443 and 170, to get
443 = 170 x 2 + 103
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 103 and 170, to get
170 = 103 x 1 + 67
Step 3: We consider the new divisor 103 and the new remainder 67, and apply the division lemma to get
103 = 67 x 1 + 36
We consider the new divisor 67 and the new remainder 36,and apply the division lemma to get
67 = 36 x 1 + 31
We consider the new divisor 36 and the new remainder 31,and apply the division lemma to get
36 = 31 x 1 + 5
We consider the new divisor 31 and the new remainder 5,and apply the division lemma to get
31 = 5 x 6 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 170 and 443 is 1
Notice that 1 = HCF(5,1) = HCF(31,5) = HCF(36,31) = HCF(67,36) = HCF(103,67) = HCF(170,103) = HCF(443,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 722 > 1, we apply the division lemma to 722 and 1, to get
722 = 1 x 722 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 722 is 1
Notice that 1 = HCF(722,1) .
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) .
