HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 788, 353 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 788, 353 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 440, 788, 353 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 440, 788, 353 is 1.
HCF(440, 788, 353) = 1
HCF of 440, 788, 353 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 788, 353 is 1.
Highest Common Factor of 440,788,353 is 1
Step 1: Since 788 > 440, we apply the division lemma to 788 and 440, to get
788 = 440 x 1 + 348
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 348 and 440, to get
440 = 348 x 1 + 92
Step 3: We consider the new divisor 348 and the new remainder 92, and apply the division lemma to get
348 = 92 x 3 + 72
We consider the new divisor 92 and the new remainder 72,and apply the division lemma to get
92 = 72 x 1 + 20
We consider the new divisor 72 and the new remainder 20,and apply the division lemma to get
72 = 20 x 3 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 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 440 and 788 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(72,20) = HCF(92,72) = HCF(348,92) = HCF(440,348) = HCF(788,440) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 353 > 4, we apply the division lemma to 353 and 4, to get
353 = 4 x 88 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 353 is 1
Notice that 1 = HCF(4,1) = HCF(353,4) .
