HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1942, 826 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 1942, 826 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 1942, 826 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 1942, 826 is 2.
HCF(1942, 826) = 2
HCF of 1942, 826 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1942, 826 is 2.
Highest Common Factor of 1942,826 is 2
Step 1: Since 1942 > 826, we apply the division lemma to 1942 and 826, to get
1942 = 826 x 2 + 290
Step 2: Since the reminder 826 ≠ 0, we apply division lemma to 290 and 826, to get
826 = 290 x 2 + 246
Step 3: We consider the new divisor 290 and the new remainder 246, and apply the division lemma to get
290 = 246 x 1 + 44
We consider the new divisor 246 and the new remainder 44,and apply the division lemma to get
246 = 44 x 5 + 26
We consider the new divisor 44 and the new remainder 26,and apply the division lemma to get
44 = 26 x 1 + 18
We consider the new divisor 26 and the new remainder 18,and apply the division lemma to get
26 = 18 x 1 + 8
We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get
18 = 8 x 2 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 1942 and 826 is 2
Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(26,18) = HCF(44,26) = HCF(246,44) = HCF(290,246) = HCF(826,290) = HCF(1942,826) .
