HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 511, 371, 656 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 511, 371, 656 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 511, 371, 656 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 511, 371, 656 is 1.
HCF(511, 371, 656) = 1
HCF of 511, 371, 656 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 511, 371, 656 is 1.
Highest Common Factor of 511,371,656 is 1
Step 1: Since 511 > 371, we apply the division lemma to 511 and 371, to get
511 = 371 x 1 + 140
Step 2: Since the reminder 371 ≠ 0, we apply division lemma to 140 and 371, to get
371 = 140 x 2 + 91
Step 3: We consider the new divisor 140 and the new remainder 91, and apply the division lemma to get
140 = 91 x 1 + 49
We consider the new divisor 91 and the new remainder 49,and apply the division lemma to get
91 = 49 x 1 + 42
We consider the new divisor 49 and the new remainder 42,and apply the division lemma to get
49 = 42 x 1 + 7
We consider the new divisor 42 and the new remainder 7,and apply the division lemma to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 511 and 371 is 7
Notice that 7 = HCF(42,7) = HCF(49,42) = HCF(91,49) = HCF(140,91) = HCF(371,140) = HCF(511,371) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 656 > 7, we apply the division lemma to 656 and 7, to get
656 = 7 x 93 + 5
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 5 and 7, to get
7 = 5 x 1 + 2
Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get
5 = 2 x 2 + 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 7 and 656 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(656,7) .
