HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 3742, 4479 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 3742, 4479 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, 3742, 4479 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, 3742, 4479 is 1.
HCF(980, 3742, 4479) = 1
HCF of 980, 3742, 4479 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, 3742, 4479 is 1.
Highest Common Factor of 980,3742,4479 is 1
Step 1: Since 3742 > 980, we apply the division lemma to 3742 and 980, to get
3742 = 980 x 3 + 802
Step 2: Since the reminder 980 ≠ 0, we apply division lemma to 802 and 980, to get
980 = 802 x 1 + 178
Step 3: We consider the new divisor 802 and the new remainder 178, and apply the division lemma to get
802 = 178 x 4 + 90
We consider the new divisor 178 and the new remainder 90,and apply the division lemma to get
178 = 90 x 1 + 88
We consider the new divisor 90 and the new remainder 88,and apply the division lemma to get
90 = 88 x 1 + 2
We consider the new divisor 88 and the new remainder 2,and apply the division lemma to get
88 = 2 x 44 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 980 and 3742 is 2
Notice that 2 = HCF(88,2) = HCF(90,88) = HCF(178,90) = HCF(802,178) = HCF(980,802) = HCF(3742,980) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 4479 > 2, we apply the division lemma to 4479 and 2, to get
4479 = 2 x 2239 + 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 4479 is 1
Notice that 1 = HCF(2,1) = HCF(4479,2) .
