HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 751, 568 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 751, 568 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 991, 751, 568 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 991, 751, 568 is 1.
HCF(991, 751, 568) = 1
HCF of 991, 751, 568 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 991, 751, 568 is 1.
Highest Common Factor of 991,751,568 is 1
Step 1: Since 991 > 751, we apply the division lemma to 991 and 751, to get
991 = 751 x 1 + 240
Step 2: Since the reminder 751 ≠ 0, we apply division lemma to 240 and 751, to get
751 = 240 x 3 + 31
Step 3: We consider the new divisor 240 and the new remainder 31, and apply the division lemma to get
240 = 31 x 7 + 23
We consider the new divisor 31 and the new remainder 23,and apply the division lemma to get
31 = 23 x 1 + 8
We consider the new divisor 23 and the new remainder 8,and apply the division lemma to get
23 = 8 x 2 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 751 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(23,8) = HCF(31,23) = HCF(240,31) = HCF(751,240) = HCF(991,751) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 568 > 1, we apply the division lemma to 568 and 1, to get
568 = 1 x 568 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 568 is 1
Notice that 1 = HCF(568,1) .
