HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 522, 671, 845 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 522, 671, 845 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 609, 522, 671, 845 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 609, 522, 671, 845 is 1.
HCF(609, 522, 671, 845) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 522, 671, 845 is 1.
Step 1: Since 609 > 522, we apply the division lemma to 609 and 522, to get
609 = 522 x 1 + 87
Step 2: Since the reminder 522 ≠ 0, we apply division lemma to 87 and 522, to get
522 = 87 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 87, the HCF of 609 and 522 is 87
Notice that 87 = HCF(522,87) = HCF(609,522) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 671 > 87, we apply the division lemma to 671 and 87, to get
671 = 87 x 7 + 62
Step 2: Since the reminder 87 ≠ 0, we apply division lemma to 62 and 87, to get
87 = 62 x 1 + 25
Step 3: We consider the new divisor 62 and the new remainder 25, and apply the division lemma to get
62 = 25 x 2 + 12
We consider the new divisor 25 and the new remainder 12,and apply the division lemma to get
25 = 12 x 2 + 1
We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 87 and 671 is 1
Notice that 1 = HCF(12,1) = HCF(25,12) = HCF(62,25) = HCF(87,62) = HCF(671,87) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 845 > 1, we apply the division lemma to 845 and 1, to get
845 = 1 x 845 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 845 is 1
Notice that 1 = HCF(845,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
