HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 238, 804, 856, 65 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 238, 804, 856, 65 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 238, 804, 856, 65 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 238, 804, 856, 65 is 1.
HCF(238, 804, 856, 65) = 1
HCF of 238, 804, 856, 65 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 238, 804, 856, 65 is 1.
Highest Common Factor of 238,804,856,65 is 1
Step 1: Since 804 > 238, we apply the division lemma to 804 and 238, to get
804 = 238 x 3 + 90
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 90 and 238, to get
238 = 90 x 2 + 58
Step 3: We consider the new divisor 90 and the new remainder 58, and apply the division lemma to get
90 = 58 x 1 + 32
We consider the new divisor 58 and the new remainder 32,and apply the division lemma to get
58 = 32 x 1 + 26
We consider the new divisor 32 and the new remainder 26,and apply the division lemma to get
32 = 26 x 1 + 6
We consider the new divisor 26 and the new remainder 6,and apply the division lemma to get
26 = 6 x 4 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 238 and 804 is 2
Notice that 2 = HCF(6,2) = HCF(26,6) = HCF(32,26) = HCF(58,32) = HCF(90,58) = HCF(238,90) = HCF(804,238) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 856 > 2, we apply the division lemma to 856 and 2, to get
856 = 2 x 428 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 856 is 2
Notice that 2 = HCF(856,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 65 > 2, we apply the division lemma to 65 and 2, to get
65 = 2 x 32 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 65 is 1
Notice that 1 = HCF(2,1) = HCF(65,2) .
