HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 488, 638, 698 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 488, 638, 698 is 2 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 488, 638, 698 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 488, 638, 698 is 2.
HCF(488, 638, 698) = 2
HCF of 488, 638, 698 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 488, 638, 698 is 2.
Highest Common Factor of 488,638,698 is 2
Step 1: Since 638 > 488, we apply the division lemma to 638 and 488, to get
638 = 488 x 1 + 150
Step 2: Since the reminder 488 ≠ 0, we apply division lemma to 150 and 488, to get
488 = 150 x 3 + 38
Step 3: We consider the new divisor 150 and the new remainder 38, and apply the division lemma to get
150 = 38 x 3 + 36
We consider the new divisor 38 and the new remainder 36,and apply the division lemma to get
38 = 36 x 1 + 2
We consider the new divisor 36 and the new remainder 2,and apply the division lemma to get
36 = 2 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 488 and 638 is 2
Notice that 2 = HCF(36,2) = HCF(38,36) = HCF(150,38) = HCF(488,150) = HCF(638,488) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 2, we apply the division lemma to 698 and 2, to get
698 = 2 x 349 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 698 is 2
Notice that 2 = HCF(698,2) .
