HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 858, 379, 837 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 858, 379, 837 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 858, 379, 837 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 858, 379, 837 is 1.
HCF(858, 379, 837) = 1
HCF of 858, 379, 837 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 858, 379, 837 is 1.
Highest Common Factor of 858,379,837 is 1
Step 1: Since 858 > 379, we apply the division lemma to 858 and 379, to get
858 = 379 x 2 + 100
Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 100 and 379, to get
379 = 100 x 3 + 79
Step 3: We consider the new divisor 100 and the new remainder 79, and apply the division lemma to get
100 = 79 x 1 + 21
We consider the new divisor 79 and the new remainder 21,and apply the division lemma to get
79 = 21 x 3 + 16
We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get
21 = 16 x 1 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 858 and 379 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(79,21) = HCF(100,79) = HCF(379,100) = HCF(858,379) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 837 > 1, we apply the division lemma to 837 and 1, to get
837 = 1 x 837 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 837 is 1
Notice that 1 = HCF(837,1) .
