HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 3220 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 123, 3220 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 123, 3220 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 123, 3220 is 1.
HCF(123, 3220) = 1
HCF of 123, 3220 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 123, 3220 is 1.
Highest Common Factor of 123,3220 is 1
Step 1: Since 3220 > 123, we apply the division lemma to 3220 and 123, to get
3220 = 123 x 26 + 22
Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 22 and 123, to get
123 = 22 x 5 + 13
Step 3: We consider the new divisor 22 and the new remainder 13, and apply the division lemma to get
22 = 13 x 1 + 9
We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get
13 = 9 x 1 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 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 123 and 3220 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(22,13) = HCF(123,22) = HCF(3220,123) .
