HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 165, 858, 956, 204 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 165, 858, 956, 204 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 165, 858, 956, 204 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 165, 858, 956, 204 is 1.
HCF(165, 858, 956, 204) = 1
HCF of 165, 858, 956, 204 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 165, 858, 956, 204 is 1.
Highest Common Factor of 165,858,956,204 is 1
Step 1: Since 858 > 165, we apply the division lemma to 858 and 165, to get
858 = 165 x 5 + 33
Step 2: Since the reminder 165 ≠ 0, we apply division lemma to 33 and 165, to get
165 = 33 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 33, the HCF of 165 and 858 is 33
Notice that 33 = HCF(165,33) = HCF(858,165) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 956 > 33, we apply the division lemma to 956 and 33, to get
956 = 33 x 28 + 32
Step 2: Since the reminder 33 ≠ 0, we apply division lemma to 32 and 33, to get
33 = 32 x 1 + 1
Step 3: We consider the new divisor 32 and the new remainder 1, and apply the division lemma to get
32 = 1 x 32 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 33 and 956 is 1
Notice that 1 = HCF(32,1) = HCF(33,32) = HCF(956,33) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 204 > 1, we apply the division lemma to 204 and 1, to get
204 = 1 x 204 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 204 is 1
Notice that 1 = HCF(204,1) .
