HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 669, 793, 395, 856 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 669, 793, 395, 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 669, 793, 395, 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 669, 793, 395, 856 is 1.
HCF(669, 793, 395, 856) = 1
HCF of 669, 793, 395, 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 669, 793, 395, 856 is 1.
Highest Common Factor of 669,793,395,856 is 1
Step 1: Since 793 > 669, we apply the division lemma to 793 and 669, to get
793 = 669 x 1 + 124
Step 2: Since the reminder 669 ≠ 0, we apply division lemma to 124 and 669, to get
669 = 124 x 5 + 49
Step 3: We consider the new divisor 124 and the new remainder 49, and apply the division lemma to get
124 = 49 x 2 + 26
We consider the new divisor 49 and the new remainder 26,and apply the division lemma to get
49 = 26 x 1 + 23
We consider the new divisor 26 and the new remainder 23,and apply the division lemma to get
26 = 23 x 1 + 3
We consider the new divisor 23 and the new remainder 3,and apply the division lemma to get
23 = 3 x 7 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 669 and 793 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(23,3) = HCF(26,23) = HCF(49,26) = HCF(124,49) = HCF(669,124) = HCF(793,669) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get
395 = 1 x 395 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1
Notice that 1 = HCF(395,1) .
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) .
