HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 609, 955, 49, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 609, 955, 49, 698 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, 955, 49, 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 609, 955, 49, 698 is 1.
HCF(609, 955, 49, 698) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 609, 955, 49, 698 is 1.
Step 1: Since 955 > 609, we apply the division lemma to 955 and 609, to get
955 = 609 x 1 + 346
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 346 and 609, to get
609 = 346 x 1 + 263
Step 3: We consider the new divisor 346 and the new remainder 263, and apply the division lemma to get
346 = 263 x 1 + 83
We consider the new divisor 263 and the new remainder 83,and apply the division lemma to get
263 = 83 x 3 + 14
We consider the new divisor 83 and the new remainder 14,and apply the division lemma to get
83 = 14 x 5 + 13
We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get
14 = 13 x 1 + 1
We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get
13 = 1 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 609 and 955 is 1
Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(83,14) = HCF(263,83) = HCF(346,263) = HCF(609,346) = HCF(955,609) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 49 > 1, we apply the division lemma to 49 and 1, to get
49 = 1 x 49 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 49 is 1
Notice that 1 = HCF(49,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 698 > 1, we apply the division lemma to 698 and 1, to get
698 = 1 x 698 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 698 is 1
Notice that 1 = HCF(698,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
