HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 697, 1489, 4537 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 697, 1489, 4537 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 697, 1489, 4537 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 697, 1489, 4537 is 1.
HCF(697, 1489, 4537) = 1
HCF of 697, 1489, 4537 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 697, 1489, 4537 is 1.
Highest Common Factor of 697,1489,4537 is 1
Step 1: Since 1489 > 697, we apply the division lemma to 1489 and 697, to get
1489 = 697 x 2 + 95
Step 2: Since the reminder 697 ≠ 0, we apply division lemma to 95 and 697, to get
697 = 95 x 7 + 32
Step 3: We consider the new divisor 95 and the new remainder 32, and apply the division lemma to get
95 = 32 x 2 + 31
We consider the new divisor 32 and the new remainder 31,and apply the division lemma to get
32 = 31 x 1 + 1
We consider the new divisor 31 and the new remainder 1,and apply the division lemma to get
31 = 1 x 31 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 697 and 1489 is 1
Notice that 1 = HCF(31,1) = HCF(32,31) = HCF(95,32) = HCF(697,95) = HCF(1489,697) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4537 > 1, we apply the division lemma to 4537 and 1, to get
4537 = 1 x 4537 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 4537 is 1
Notice that 1 = HCF(4537,1) .
