HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 912, 788, 647, 16 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 912, 788, 647, 16 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 912, 788, 647, 16 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 912, 788, 647, 16 is 1.
HCF(912, 788, 647, 16) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 912, 788, 647, 16 is 1.
Step 1: Since 912 > 788, we apply the division lemma to 912 and 788, to get
912 = 788 x 1 + 124
Step 2: Since the reminder 788 ≠ 0, we apply division lemma to 124 and 788, to get
788 = 124 x 6 + 44
Step 3: We consider the new divisor 124 and the new remainder 44, and apply the division lemma to get
124 = 44 x 2 + 36
We consider the new divisor 44 and the new remainder 36,and apply the division lemma to get
44 = 36 x 1 + 8
We consider the new divisor 36 and the new remainder 8,and apply the division lemma to get
36 = 8 x 4 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 912 and 788 is 4
Notice that 4 = HCF(8,4) = HCF(36,8) = HCF(44,36) = HCF(124,44) = HCF(788,124) = HCF(912,788) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 4, we apply the division lemma to 647 and 4, to get
647 = 4 x 161 + 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 647 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(647,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 16 > 1, we apply the division lemma to 16 and 1, to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 16 is 1
Notice that 1 = HCF(16,1) .
