HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 425, 450, 172 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 425, 450, 172 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 425, 450, 172 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 425, 450, 172 is 1.
HCF(425, 450, 172) = 1
HCF of 425, 450, 172 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 425, 450, 172 is 1.
Highest Common Factor of 425,450,172 is 1
Step 1: Since 450 > 425, we apply the division lemma to 450 and 425, to get
450 = 425 x 1 + 25
Step 2: Since the reminder 425 ≠ 0, we apply division lemma to 25 and 425, to get
425 = 25 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 425 and 450 is 25
Notice that 25 = HCF(425,25) = HCF(450,425) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 172 > 25, we apply the division lemma to 172 and 25, to get
172 = 25 x 6 + 22
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 22 and 25, to get
25 = 22 x 1 + 3
Step 3: We consider the new divisor 22 and the new remainder 3, and apply the division lemma to get
22 = 3 x 7 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 25 and 172 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(25,22) = HCF(172,25) .
