HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 698, 639, 348, 11 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 698, 639, 348, 11 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 698, 639, 348, 11 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 698, 639, 348, 11 is 1.
HCF(698, 639, 348, 11) = 1
HCF of 698, 639, 348, 11 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 698, 639, 348, 11 is 1.
Highest Common Factor of 698,639,348,11 is 1
Step 1: Since 698 > 639, we apply the division lemma to 698 and 639, to get
698 = 639 x 1 + 59
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 59 and 639, to get
639 = 59 x 10 + 49
Step 3: We consider the new divisor 59 and the new remainder 49, and apply the division lemma to get
59 = 49 x 1 + 10
We consider the new divisor 49 and the new remainder 10,and apply the division lemma to get
49 = 10 x 4 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 698 and 639 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(49,10) = HCF(59,49) = HCF(639,59) = HCF(698,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 348 > 1, we apply the division lemma to 348 and 1, to get
348 = 1 x 348 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 348 is 1
Notice that 1 = HCF(348,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 11 > 1, we apply the division lemma to 11 and 1, to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 11 is 1
Notice that 1 = HCF(11,1) .
