HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 679, 203, 960 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 679, 203, 960 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 980, 679, 203, 960 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 980, 679, 203, 960 is 1.
HCF(980, 679, 203, 960) = 1
HCF of 980, 679, 203, 960 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 980, 679, 203, 960 is 1.
Highest Common Factor of 980,679,203,960 is 1
Step 1: Since 980 > 679, we apply the division lemma to 980 and 679, to get
980 = 679 x 1 + 301
Step 2: Since the reminder 679 ≠ 0, we apply division lemma to 301 and 679, to get
679 = 301 x 2 + 77
Step 3: We consider the new divisor 301 and the new remainder 77, and apply the division lemma to get
301 = 77 x 3 + 70
We consider the new divisor 77 and the new remainder 70,and apply the division lemma to get
77 = 70 x 1 + 7
We consider the new divisor 70 and the new remainder 7,and apply the division lemma to get
70 = 7 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 980 and 679 is 7
Notice that 7 = HCF(70,7) = HCF(77,70) = HCF(301,77) = HCF(679,301) = HCF(980,679) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 203 > 7, we apply the division lemma to 203 and 7, to get
203 = 7 x 29 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 7 and 203 is 7
Notice that 7 = HCF(203,7) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 960 > 7, we apply the division lemma to 960 and 7, to get
960 = 7 x 137 + 1
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 1 and 7, to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 7 and 960 is 1
Notice that 1 = HCF(7,1) = HCF(960,7) .
