HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 410, 619 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 986, 410, 619 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 986, 410, 619 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 986, 410, 619 is 1.
HCF(986, 410, 619) = 1
HCF of 986, 410, 619 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 986, 410, 619 is 1.
Highest Common Factor of 986,410,619 is 1
Step 1: Since 986 > 410, we apply the division lemma to 986 and 410, to get
986 = 410 x 2 + 166
Step 2: Since the reminder 410 ≠ 0, we apply division lemma to 166 and 410, to get
410 = 166 x 2 + 78
Step 3: We consider the new divisor 166 and the new remainder 78, and apply the division lemma to get
166 = 78 x 2 + 10
We consider the new divisor 78 and the new remainder 10,and apply the division lemma to get
78 = 10 x 7 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 410 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(78,10) = HCF(166,78) = HCF(410,166) = HCF(986,410) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 619 > 2, we apply the division lemma to 619 and 2, to get
619 = 2 x 309 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 619 is 1
Notice that 1 = HCF(2,1) = HCF(619,2) .
