HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1912, 4642 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 1912, 4642 is 2 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 1912, 4642 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 1912, 4642 is 2.
HCF(1912, 4642) = 2
HCF of 1912, 4642 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1912, 4642 is 2.
Highest Common Factor of 1912,4642 is 2
Step 1: Since 4642 > 1912, we apply the division lemma to 4642 and 1912, to get
4642 = 1912 x 2 + 818
Step 2: Since the reminder 1912 ≠ 0, we apply division lemma to 818 and 1912, to get
1912 = 818 x 2 + 276
Step 3: We consider the new divisor 818 and the new remainder 276, and apply the division lemma to get
818 = 276 x 2 + 266
We consider the new divisor 276 and the new remainder 266,and apply the division lemma to get
276 = 266 x 1 + 10
We consider the new divisor 266 and the new remainder 10,and apply the division lemma to get
266 = 10 x 26 + 6
We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1912 and 4642 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(266,10) = HCF(276,266) = HCF(818,276) = HCF(1912,818) = HCF(4642,1912) .
