HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 539, 968, 645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 539, 968, 645 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 539, 968, 645 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 539, 968, 645 is 1.
HCF(539, 968, 645) = 1
HCF of 539, 968, 645 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 539, 968, 645 is 1.
Highest Common Factor of 539,968,645 is 1
Step 1: Since 968 > 539, we apply the division lemma to 968 and 539, to get
968 = 539 x 1 + 429
Step 2: Since the reminder 539 ≠ 0, we apply division lemma to 429 and 539, to get
539 = 429 x 1 + 110
Step 3: We consider the new divisor 429 and the new remainder 110, and apply the division lemma to get
429 = 110 x 3 + 99
We consider the new divisor 110 and the new remainder 99,and apply the division lemma to get
110 = 99 x 1 + 11
We consider the new divisor 99 and the new remainder 11,and apply the division lemma to get
99 = 11 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 539 and 968 is 11
Notice that 11 = HCF(99,11) = HCF(110,99) = HCF(429,110) = HCF(539,429) = HCF(968,539) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 645 > 11, we apply the division lemma to 645 and 11, to get
645 = 11 x 58 + 7
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 7 and 11, to get
11 = 7 x 1 + 4
Step 3: We consider the new divisor 7 and the new remainder 4, and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 645 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(11,7) = HCF(645,11) .
