HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 7844 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 690, 7844 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 690, 7844 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 690, 7844 is 2.
HCF(690, 7844) = 2
HCF of 690, 7844 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 690, 7844 is 2.
Highest Common Factor of 690,7844 is 2
Step 1: Since 7844 > 690, we apply the division lemma to 7844 and 690, to get
7844 = 690 x 11 + 254
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 254 and 690, to get
690 = 254 x 2 + 182
Step 3: We consider the new divisor 254 and the new remainder 182, and apply the division lemma to get
254 = 182 x 1 + 72
We consider the new divisor 182 and the new remainder 72,and apply the division lemma to get
182 = 72 x 2 + 38
We consider the new divisor 72 and the new remainder 38,and apply the division lemma to get
72 = 38 x 1 + 34
We consider the new divisor 38 and the new remainder 34,and apply the division lemma to get
38 = 34 x 1 + 4
We consider the new divisor 34 and the new remainder 4,and apply the division lemma to get
34 = 4 x 8 + 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 690 and 7844 is 2
Notice that 2 = HCF(4,2) = HCF(34,4) = HCF(38,34) = HCF(72,38) = HCF(182,72) = HCF(254,182) = HCF(690,254) = HCF(7844,690) .
