HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 775, 858, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 775, 858, 856 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 775, 858, 856 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 775, 858, 856 is 1.
HCF(775, 858, 856) = 1
HCF of 775, 858, 856 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 775, 858, 856 is 1.
Highest Common Factor of 775,858,856 is 1
Step 1: Since 858 > 775, we apply the division lemma to 858 and 775, to get
858 = 775 x 1 + 83
Step 2: Since the reminder 775 ≠ 0, we apply division lemma to 83 and 775, to get
775 = 83 x 9 + 28
Step 3: We consider the new divisor 83 and the new remainder 28, and apply the division lemma to get
83 = 28 x 2 + 27
We consider the new divisor 28 and the new remainder 27,and apply the division lemma to get
28 = 27 x 1 + 1
We consider the new divisor 27 and the new remainder 1,and apply the division lemma to get
27 = 1 x 27 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 775 and 858 is 1
Notice that 1 = HCF(27,1) = HCF(28,27) = HCF(83,28) = HCF(775,83) = HCF(858,775) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 1, we apply the division lemma to 856 and 1, to get
856 = 1 x 856 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 856 is 1
Notice that 1 = HCF(856,1) .
