HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 751, 59 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 645, 751, 59 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 645, 751, 59 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 645, 751, 59 is 1.
HCF(645, 751, 59) = 1
HCF of 645, 751, 59 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 645, 751, 59 is 1.
Highest Common Factor of 645,751,59 is 1
Step 1: Since 751 > 645, we apply the division lemma to 751 and 645, to get
751 = 645 x 1 + 106
Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 106 and 645, to get
645 = 106 x 6 + 9
Step 3: 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 645 and 751 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(106,9) = HCF(645,106) = HCF(751,645) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 59 > 1, we apply the division lemma to 59 and 1, to get
59 = 1 x 59 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 59 is 1
Notice that 1 = HCF(59,1) .
