HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 749, 590 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 749, 590 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 398, 749, 590 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 398, 749, 590 is 1.
HCF(398, 749, 590) = 1
HCF of 398, 749, 590 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 749, 590 is 1.
Highest Common Factor of 398,749,590 is 1
Step 1: Since 749 > 398, we apply the division lemma to 749 and 398, to get
749 = 398 x 1 + 351
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 351 and 398, to get
398 = 351 x 1 + 47
Step 3: We consider the new divisor 351 and the new remainder 47, and apply the division lemma to get
351 = 47 x 7 + 22
We consider the new divisor 47 and the new remainder 22,and apply the division lemma to get
47 = 22 x 2 + 3
We consider the new divisor 22 and the new remainder 3,and apply the division lemma to get
22 = 3 x 7 + 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 398 and 749 is 1
Notice that 1 = HCF(3,1) = HCF(22,3) = HCF(47,22) = HCF(351,47) = HCF(398,351) = HCF(749,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 590 > 1, we apply the division lemma to 590 and 1, to get
590 = 1 x 590 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 590 is 1
Notice that 1 = HCF(590,1) .
