HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 32525 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 32525 is 5 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 655, 32525 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 655, 32525 is 5.
HCF(655, 32525) = 5
HCF of 655, 32525 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 655, 32525 is 5.
Highest Common Factor of 655,32525 is 5
Step 1: Since 32525 > 655, we apply the division lemma to 32525 and 655, to get
32525 = 655 x 49 + 430
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 430 and 655, to get
655 = 430 x 1 + 225
Step 3: We consider the new divisor 430 and the new remainder 225, and apply the division lemma to get
430 = 225 x 1 + 205
We consider the new divisor 225 and the new remainder 205,and apply the division lemma to get
225 = 205 x 1 + 20
We consider the new divisor 205 and the new remainder 20,and apply the division lemma to get
205 = 20 x 10 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 655 and 32525 is 5
Notice that 5 = HCF(20,5) = HCF(205,20) = HCF(225,205) = HCF(430,225) = HCF(655,430) = HCF(32525,655) .
