HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 456, 808 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 456, 808 is 4 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, 456, 808 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, 456, 808 is 4.
HCF(788, 456, 808) = 4
HCF of 788, 456, 808 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, 456, 808 is 4.
Highest Common Factor of 788,456,808 is 4
Step 1: Since 788 > 456, we apply the division lemma to 788 and 456, to get
788 = 456 x 1 + 332
Step 2: Since the reminder 456 ≠ 0, we apply division lemma to 332 and 456, to get
456 = 332 x 1 + 124
Step 3: We consider the new divisor 332 and the new remainder 124, and apply the division lemma to get
332 = 124 x 2 + 84
We consider the new divisor 124 and the new remainder 84,and apply the division lemma to get
124 = 84 x 1 + 40
We consider the new divisor 84 and the new remainder 40,and apply the division lemma to get
84 = 40 x 2 + 4
We consider the new divisor 40 and the new remainder 4,and apply the division lemma to get
40 = 4 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 788 and 456 is 4
Notice that 4 = HCF(40,4) = HCF(84,40) = HCF(124,84) = HCF(332,124) = HCF(456,332) = HCF(788,456) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 808 > 4, we apply the division lemma to 808 and 4, to get
808 = 4 x 202 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 808 is 4
Notice that 4 = HCF(808,4) .
