HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 548, 980 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 548, 980 is 4 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 548, 980 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 548, 980 is 4.
HCF(548, 980) = 4
HCF of 548, 980 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 548, 980 is 4.
Highest Common Factor of 548,980 is 4
Step 1: Since 980 > 548, we apply the division lemma to 980 and 548, to get
980 = 548 x 1 + 432
Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 432 and 548, to get
548 = 432 x 1 + 116
Step 3: We consider the new divisor 432 and the new remainder 116, and apply the division lemma to get
432 = 116 x 3 + 84
We consider the new divisor 116 and the new remainder 84,and apply the division lemma to get
116 = 84 x 1 + 32
We consider the new divisor 84 and the new remainder 32,and apply the division lemma to get
84 = 32 x 2 + 20
We consider the new divisor 32 and the new remainder 20,and apply the division lemma to get
32 = 20 x 1 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 548 and 980 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(32,20) = HCF(84,32) = HCF(116,84) = HCF(432,116) = HCF(548,432) = HCF(980,548) .
