HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 7228 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 7228 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 785, 7228 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 785, 7228 is 1.
HCF(785, 7228) = 1
HCF of 785, 7228 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 7228 is 1.
Highest Common Factor of 785,7228 is 1
Step 1: Since 7228 > 785, we apply the division lemma to 7228 and 785, to get
7228 = 785 x 9 + 163
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 163 and 785, to get
785 = 163 x 4 + 133
Step 3: We consider the new divisor 163 and the new remainder 133, and apply the division lemma to get
163 = 133 x 1 + 30
We consider the new divisor 133 and the new remainder 30,and apply the division lemma to get
133 = 30 x 4 + 13
We consider the new divisor 30 and the new remainder 13,and apply the division lemma to get
30 = 13 x 2 + 4
We consider the new divisor 13 and the new remainder 4,and apply the division lemma to get
13 = 4 x 3 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 7228 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) = HCF(30,13) = HCF(133,30) = HCF(163,133) = HCF(785,163) = HCF(7228,785) .
