HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 684, 347 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 684, 347 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 788, 684, 347 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 788, 684, 347 is 1.
HCF(788, 684, 347) = 1
HCF of 788, 684, 347 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 684, 347 is 1.
Highest Common Factor of 788,684,347 is 1
Step 1: Since 788 > 684, we apply the division lemma to 788 and 684, to get
788 = 684 x 1 + 104
Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 104 and 684, to get
684 = 104 x 6 + 60
Step 3: We consider the new divisor 104 and the new remainder 60, and apply the division lemma to get
104 = 60 x 1 + 44
We consider the new divisor 60 and the new remainder 44,and apply the division lemma to get
60 = 44 x 1 + 16
We consider the new divisor 44 and the new remainder 16,and apply the division lemma to get
44 = 16 x 2 + 12
We consider the new divisor 16 and the new remainder 12,and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4,and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 788 and 684 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(44,16) = HCF(60,44) = HCF(104,60) = HCF(684,104) = HCF(788,684) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 347 > 4, we apply the division lemma to 347 and 4, to get
347 = 4 x 86 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 347 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(347,4) .
