HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 649, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 812, 649, 775 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 812, 649, 775 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 812, 649, 775 is 1.
HCF(812, 649, 775) = 1
HCF of 812, 649, 775 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 812, 649, 775 is 1.
Highest Common Factor of 812,649,775 is 1
Step 1: Since 812 > 649, we apply the division lemma to 812 and 649, to get
812 = 649 x 1 + 163
Step 2: Since the reminder 649 ≠ 0, we apply division lemma to 163 and 649, to get
649 = 163 x 3 + 160
Step 3: We consider the new divisor 163 and the new remainder 160, and apply the division lemma to get
163 = 160 x 1 + 3
We consider the new divisor 160 and the new remainder 3,and apply the division lemma to get
160 = 3 x 53 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 812 and 649 is 1
Notice that 1 = HCF(3,1) = HCF(160,3) = HCF(163,160) = HCF(649,163) = HCF(812,649) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 775 > 1, we apply the division lemma to 775 and 1, to get
775 = 1 x 775 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 775 is 1
Notice that 1 = HCF(775,1) .
