HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 498, 419 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 498, 419 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 679, 498, 419 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 679, 498, 419 is 1.
HCF(679, 498, 419) = 1
HCF of 679, 498, 419 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 679, 498, 419 is 1.
Highest Common Factor of 679,498,419 is 1
Step 1: Since 679 > 498, we apply the division lemma to 679 and 498, to get
679 = 498 x 1 + 181
Step 2: Since the reminder 498 ≠ 0, we apply division lemma to 181 and 498, to get
498 = 181 x 2 + 136
Step 3: We consider the new divisor 181 and the new remainder 136, and apply the division lemma to get
181 = 136 x 1 + 45
We consider the new divisor 136 and the new remainder 45,and apply the division lemma to get
136 = 45 x 3 + 1
We consider the new divisor 45 and the new remainder 1,and apply the division lemma to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 679 and 498 is 1
Notice that 1 = HCF(45,1) = HCF(136,45) = HCF(181,136) = HCF(498,181) = HCF(679,498) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 419 > 1, we apply the division lemma to 419 and 1, to get
419 = 1 x 419 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 419 is 1
Notice that 1 = HCF(419,1) .
