HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 620, 879 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 620, 879 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, 620, 879 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, 620, 879 is 1.
HCF(679, 620, 879) = 1
HCF of 679, 620, 879 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, 620, 879 is 1.
Highest Common Factor of 679,620,879 is 1
Step 1: Since 679 > 620, we apply the division lemma to 679 and 620, to get
679 = 620 x 1 + 59
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 59 and 620, to get
620 = 59 x 10 + 30
Step 3: We consider the new divisor 59 and the new remainder 30, and apply the division lemma to get
59 = 30 x 1 + 29
We consider the new divisor 30 and the new remainder 29,and apply the division lemma to get
30 = 29 x 1 + 1
We consider the new divisor 29 and the new remainder 1,and apply the division lemma to get
29 = 1 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 679 and 620 is 1
Notice that 1 = HCF(29,1) = HCF(30,29) = HCF(59,30) = HCF(620,59) = HCF(679,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 879 > 1, we apply the division lemma to 879 and 1, to get
879 = 1 x 879 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 879 is 1
Notice that 1 = HCF(879,1) .
