HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 825, 675 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 655, 825, 675 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, 825, 675 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, 825, 675 is 5.
HCF(655, 825, 675) = 5
HCF of 655, 825, 675 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, 825, 675 is 5.
Highest Common Factor of 655,825,675 is 5
Step 1: Since 825 > 655, we apply the division lemma to 825 and 655, to get
825 = 655 x 1 + 170
Step 2: Since the reminder 655 ≠ 0, we apply division lemma to 170 and 655, to get
655 = 170 x 3 + 145
Step 3: We consider the new divisor 170 and the new remainder 145, and apply the division lemma to get
170 = 145 x 1 + 25
We consider the new divisor 145 and the new remainder 25,and apply the division lemma to get
145 = 25 x 5 + 20
We consider the new divisor 25 and the new remainder 20,and apply the division lemma to get
25 = 20 x 1 + 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 825 is 5
Notice that 5 = HCF(20,5) = HCF(25,20) = HCF(145,25) = HCF(170,145) = HCF(655,170) = HCF(825,655) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 675 > 5, we apply the division lemma to 675 and 5, to get
675 = 5 x 135 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 675 is 5
Notice that 5 = HCF(675,5) .
