HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 172, 647, 567 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 172, 647, 567 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 172, 647, 567 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 172, 647, 567 is 1.
HCF(172, 647, 567) = 1
HCF of 172, 647, 567 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 172, 647, 567 is 1.
Highest Common Factor of 172,647,567 is 1
Step 1: Since 647 > 172, we apply the division lemma to 647 and 172, to get
647 = 172 x 3 + 131
Step 2: Since the reminder 172 ≠ 0, we apply division lemma to 131 and 172, to get
172 = 131 x 1 + 41
Step 3: We consider the new divisor 131 and the new remainder 41, and apply the division lemma to get
131 = 41 x 3 + 8
We consider the new divisor 41 and the new remainder 8,and apply the division lemma to get
41 = 8 x 5 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 172 and 647 is 1
Notice that 1 = HCF(8,1) = HCF(41,8) = HCF(131,41) = HCF(172,131) = HCF(647,172) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 567 > 1, we apply the division lemma to 567 and 1, to get
567 = 1 x 567 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 567 is 1
Notice that 1 = HCF(567,1) .
