HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 794, 934 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 794, 934 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 685, 794, 934 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 685, 794, 934 is 1.
HCF(685, 794, 934) = 1
HCF of 685, 794, 934 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 685, 794, 934 is 1.
Highest Common Factor of 685,794,934 is 1
Step 1: Since 794 > 685, we apply the division lemma to 794 and 685, to get
794 = 685 x 1 + 109
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 109 and 685, to get
685 = 109 x 6 + 31
Step 3: We consider the new divisor 109 and the new remainder 31, and apply the division lemma to get
109 = 31 x 3 + 16
We consider the new divisor 31 and the new remainder 16,and apply the division lemma to get
31 = 16 x 1 + 15
We consider the new divisor 16 and the new remainder 15,and apply the division lemma to get
16 = 15 x 1 + 1
We consider the new divisor 15 and the new remainder 1,and apply the division lemma to get
15 = 1 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 685 and 794 is 1
Notice that 1 = HCF(15,1) = HCF(16,15) = HCF(31,16) = HCF(109,31) = HCF(685,109) = HCF(794,685) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 934 > 1, we apply the division lemma to 934 and 1, to get
934 = 1 x 934 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 934 is 1
Notice that 1 = HCF(934,1) .
