HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 794, 690 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 794, 690 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 794, 690 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 794, 690 is 2.
HCF(794, 690) = 2
HCF of 794, 690 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 794, 690 is 2.
Highest Common Factor of 794,690 is 2
Step 1: Since 794 > 690, we apply the division lemma to 794 and 690, to get
794 = 690 x 1 + 104
Step 2: Since the reminder 690 ≠ 0, we apply division lemma to 104 and 690, to get
690 = 104 x 6 + 66
Step 3: We consider the new divisor 104 and the new remainder 66, and apply the division lemma to get
104 = 66 x 1 + 38
We consider the new divisor 66 and the new remainder 38,and apply the division lemma to get
66 = 38 x 1 + 28
We consider the new divisor 38 and the new remainder 28,and apply the division lemma to get
38 = 28 x 1 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 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 794 and 690 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(38,28) = HCF(66,38) = HCF(104,66) = HCF(690,104) = HCF(794,690) .
