HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 833, 266, 770 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 833, 266, 770 is 7 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 833, 266, 770 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 833, 266, 770 is 7.
HCF(833, 266, 770) = 7
HCF of 833, 266, 770 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 833, 266, 770 is 7.
Highest Common Factor of 833,266,770 is 7
Step 1: Since 833 > 266, we apply the division lemma to 833 and 266, to get
833 = 266 x 3 + 35
Step 2: Since the reminder 266 ≠ 0, we apply division lemma to 35 and 266, to get
266 = 35 x 7 + 21
Step 3: We consider the new divisor 35 and the new remainder 21, and apply the division lemma to get
35 = 21 x 1 + 14
We consider the new divisor 21 and the new remainder 14,and apply the division lemma to get
21 = 14 x 1 + 7
We consider the new divisor 14 and the new remainder 7,and apply the division lemma to get
14 = 7 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 833 and 266 is 7
Notice that 7 = HCF(14,7) = HCF(21,14) = HCF(35,21) = HCF(266,35) = HCF(833,266) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 770 > 7, we apply the division lemma to 770 and 7, to get
770 = 7 x 110 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 770 is 7
Notice that 7 = HCF(770,7) .
