HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 61, 94, 855 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 61, 94, 855 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 61, 94, 855 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 61, 94, 855 is 1.
HCF(61, 94, 855) = 1
HCF of 61, 94, 855 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 61, 94, 855 is 1.
Highest Common Factor of 61,94,855 is 1
Step 1: Since 94 > 61, we apply the division lemma to 94 and 61, to get
94 = 61 x 1 + 33
Step 2: Since the reminder 61 ≠ 0, we apply division lemma to 33 and 61, to get
61 = 33 x 1 + 28
Step 3: We consider the new divisor 33 and the new remainder 28, and apply the division lemma to get
33 = 28 x 1 + 5
We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get
28 = 5 x 5 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 61 and 94 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(33,28) = HCF(61,33) = HCF(94,61) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 855 > 1, we apply the division lemma to 855 and 1, to get
855 = 1 x 855 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 855 is 1
Notice that 1 = HCF(855,1) .
