HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 55, 72, 25, 632 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 55, 72, 25, 632 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 55, 72, 25, 632 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 55, 72, 25, 632 is 1.
HCF(55, 72, 25, 632) = 1
HCF of 55, 72, 25, 632 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 55, 72, 25, 632 is 1.
Highest Common Factor of 55,72,25,632 is 1
Step 1: Since 72 > 55, we apply the division lemma to 72 and 55, to get
72 = 55 x 1 + 17
Step 2: Since the reminder 55 ≠ 0, we apply division lemma to 17 and 55, to get
55 = 17 x 3 + 4
Step 3: We consider the new divisor 17 and the new remainder 4, and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma 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 55 and 72 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(72,55) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 25 > 1, we apply the division lemma to 25 and 1, to get
25 = 1 x 25 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 25 is 1
Notice that 1 = HCF(25,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 632 > 1, we apply the division lemma to 632 and 1, to get
632 = 1 x 632 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 632 is 1
Notice that 1 = HCF(632,1) .
