HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 955, 665 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 955, 665 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 955, 665 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 955, 665 is 5.
HCF(955, 665) = 5
HCF of 955, 665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 955, 665 is 5.
Highest Common Factor of 955,665 is 5
Step 1: Since 955 > 665, we apply the division lemma to 955 and 665, to get
955 = 665 x 1 + 290
Step 2: Since the reminder 665 ≠ 0, we apply division lemma to 290 and 665, to get
665 = 290 x 2 + 85
Step 3: We consider the new divisor 290 and the new remainder 85, and apply the division lemma to get
290 = 85 x 3 + 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 955 and 665 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(85,35) = HCF(290,85) = HCF(665,290) = HCF(955,665) .
