HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 855, 380, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 855, 380, 51 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 855, 380, 51 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 855, 380, 51 is 1.
HCF(855, 380, 51) = 1
HCF of 855, 380, 51 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 855, 380, 51 is 1.
Highest Common Factor of 855,380,51 is 1
Step 1: Since 855 > 380, we apply the division lemma to 855 and 380, to get
855 = 380 x 2 + 95
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 95 and 380, to get
380 = 95 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 95, the HCF of 855 and 380 is 95
Notice that 95 = HCF(380,95) = HCF(855,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 95 > 51, we apply the division lemma to 95 and 51, to get
95 = 51 x 1 + 44
Step 2: Since the reminder 51 ≠ 0, we apply division lemma to 44 and 51, to get
51 = 44 x 1 + 7
Step 3: We consider the new divisor 44 and the new remainder 7, and apply the division lemma to get
44 = 7 x 6 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 95 and 51 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(44,7) = HCF(51,44) = HCF(95,51) .
