HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 955 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 628, 955 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 628, 955 is 1.
HCF(628, 955) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 955 is 1.
Step 1: Since 955 > 628, we apply the division lemma to 955 and 628, to get
955 = 628 x 1 + 327
Step 2: Since the reminder 628 ≠ 0, we apply division lemma to 327 and 628, to get
628 = 327 x 1 + 301
Step 3: We consider the new divisor 327 and the new remainder 301, and apply the division lemma to get
327 = 301 x 1 + 26
We consider the new divisor 301 and the new remainder 26,and apply the division lemma to get
301 = 26 x 11 + 15
We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get
26 = 15 x 1 + 11
We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get
15 = 11 x 1 + 4
We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get
11 = 4 x 2 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 628 and 955 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(301,26) = HCF(327,301) = HCF(628,327) = HCF(955,628) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?
