HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 557, 336, 791 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 557, 336, 791 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 557, 336, 791 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 557, 336, 791 is 1.
HCF(557, 336, 791) = 1
HCF of 557, 336, 791 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 557, 336, 791 is 1.
Highest Common Factor of 557,336,791 is 1
Step 1: Since 557 > 336, we apply the division lemma to 557 and 336, to get
557 = 336 x 1 + 221
Step 2: Since the reminder 336 ≠ 0, we apply division lemma to 221 and 336, to get
336 = 221 x 1 + 115
Step 3: We consider the new divisor 221 and the new remainder 115, and apply the division lemma to get
221 = 115 x 1 + 106
We consider the new divisor 115 and the new remainder 106,and apply the division lemma to get
115 = 106 x 1 + 9
We consider the new divisor 106 and the new remainder 9,and apply the division lemma to get
106 = 9 x 11 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 557 and 336 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(106,9) = HCF(115,106) = HCF(221,115) = HCF(336,221) = HCF(557,336) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 791 > 1, we apply the division lemma to 791 and 1, to get
791 = 1 x 791 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 791 is 1
Notice that 1 = HCF(791,1) .
