HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 616, 788, 478, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 616, 788, 478, 51 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 616, 788, 478, 51 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 616, 788, 478, 51 is 1.
HCF(616, 788, 478, 51) = 1
HCF of 616, 788, 478, 51 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 616, 788, 478, 51 is 1.
Highest Common Factor of 616,788,478,51 is 1
Step 1: Since 788 > 616, we apply the division lemma to 788 and 616, to get
788 = 616 x 1 + 172
Step 2: Since the reminder 616 ≠ 0, we apply division lemma to 172 and 616, to get
616 = 172 x 3 + 100
Step 3: We consider the new divisor 172 and the new remainder 100, and apply the division lemma to get
172 = 100 x 1 + 72
We consider the new divisor 100 and the new remainder 72,and apply the division lemma to get
100 = 72 x 1 + 28
We consider the new divisor 72 and the new remainder 28,and apply the division lemma to get
72 = 28 x 2 + 16
We consider the new divisor 28 and the new remainder 16,and apply the division lemma to get
28 = 16 x 1 + 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 616 and 788 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(28,16) = HCF(72,28) = HCF(100,72) = HCF(172,100) = HCF(616,172) = HCF(788,616) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 478 > 4, we apply the division lemma to 478 and 4, to get
478 = 4 x 119 + 2
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 2 and 4, to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 4 and 478 is 2
Notice that 2 = HCF(4,2) = HCF(478,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 2, we apply the division lemma to 51 and 2, to get
51 = 2 x 25 + 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 51 is 1
Notice that 1 = HCF(2,1) = HCF(51,2) .
