HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 858, 939 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 195, 858, 939 is 3 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 195, 858, 939 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 195, 858, 939 is 3.
HCF(195, 858, 939) = 3
HCF of 195, 858, 939 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 195, 858, 939 is 3.
Highest Common Factor of 195,858,939 is 3
Step 1: Since 858 > 195, we apply the division lemma to 858 and 195, to get
858 = 195 x 4 + 78
Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 78 and 195, to get
195 = 78 x 2 + 39
Step 3: We consider the new divisor 78 and the new remainder 39, and apply the division lemma to get
78 = 39 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 195 and 858 is 39
Notice that 39 = HCF(78,39) = HCF(195,78) = HCF(858,195) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 939 > 39, we apply the division lemma to 939 and 39, to get
939 = 39 x 24 + 3
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 3 and 39, to get
39 = 3 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 39 and 939 is 3
Notice that 3 = HCF(39,3) = HCF(939,39) .
