HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 991, 757, 591, 141 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 991, 757, 591, 141 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, 757, 591, 141 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, 757, 591, 141 is 1.
HCF(991, 757, 591, 141) = 1
HCF of 991, 757, 591, 141 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, 757, 591, 141 is 1.
Highest Common Factor of 991,757,591,141 is 1
Step 1: Since 991 > 757, we apply the division lemma to 991 and 757, to get
991 = 757 x 1 + 234
Step 2: Since the reminder 757 ≠ 0, we apply division lemma to 234 and 757, to get
757 = 234 x 3 + 55
Step 3: We consider the new divisor 234 and the new remainder 55, and apply the division lemma to get
234 = 55 x 4 + 14
We consider the new divisor 55 and the new remainder 14,and apply the division lemma to get
55 = 14 x 3 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 991 and 757 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(55,14) = HCF(234,55) = HCF(757,234) = HCF(991,757) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 591 > 1, we apply the division lemma to 591 and 1, to get
591 = 1 x 591 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 591 is 1
Notice that 1 = HCF(591,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 141 > 1, we apply the division lemma to 141 and 1, to get
141 = 1 x 141 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 141 is 1
Notice that 1 = HCF(141,1) .
