HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 649, 435, 539 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 649, 435, 539 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 649, 435, 539 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 649, 435, 539 is 1.
HCF(649, 435, 539) = 1
HCF of 649, 435, 539 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 649, 435, 539 is 1.
Highest Common Factor of 649,435,539 is 1
Step 1: Since 649 > 435, we apply the division lemma to 649 and 435, to get
649 = 435 x 1 + 214
Step 2: Since the reminder 435 ≠ 0, we apply division lemma to 214 and 435, to get
435 = 214 x 2 + 7
Step 3: We consider the new divisor 214 and the new remainder 7, and apply the division lemma to get
214 = 7 x 30 + 4
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 649 and 435 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(214,7) = HCF(435,214) = HCF(649,435) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 539 > 1, we apply the division lemma to 539 and 1, to get
539 = 1 x 539 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 539 is 1
Notice that 1 = HCF(539,1) .
