HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 325 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 325 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 770, 325 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 770, 325 is 5.
HCF(770, 325) = 5
HCF of 770, 325 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 325 is 5.
Highest Common Factor of 770,325 is 5
Step 1: Since 770 > 325, we apply the division lemma to 770 and 325, to get
770 = 325 x 2 + 120
Step 2: Since the reminder 325 ≠ 0, we apply division lemma to 120 and 325, to get
325 = 120 x 2 + 85
Step 3: We consider the new divisor 120 and the new remainder 85, and apply the division lemma to get
120 = 85 x 1 + 35
We consider the new divisor 85 and the new remainder 35,and apply the division lemma to get
85 = 35 x 2 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 770 and 325 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(85,35) = HCF(120,85) = HCF(325,120) = HCF(770,325) .
