HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 792, 96 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 792, 96 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, 792, 96 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, 792, 96 is 1.
HCF(685, 792, 96) = 1
HCF of 685, 792, 96 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, 792, 96 is 1.
Highest Common Factor of 685,792,96 is 1
Step 1: Since 792 > 685, we apply the division lemma to 792 and 685, to get
792 = 685 x 1 + 107
Step 2: Since the reminder 685 ≠ 0, we apply division lemma to 107 and 685, to get
685 = 107 x 6 + 43
Step 3: We consider the new divisor 107 and the new remainder 43, and apply the division lemma to get
107 = 43 x 2 + 21
We consider the new divisor 43 and the new remainder 21,and apply the division lemma to get
43 = 21 x 2 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 685 and 792 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(107,43) = HCF(685,107) = HCF(792,685) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 96 > 1, we apply the division lemma to 96 and 1, to get
96 = 1 x 96 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 96 is 1
Notice that 1 = HCF(96,1) .
