HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 980, 1533 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 980, 1533 is 7 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, 1533 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, 1533 is 7.
HCF(980, 1533) = 7
HCF of 980, 1533 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, 1533 is 7.
Highest Common Factor of 980,1533 is 7
Step 1: Since 1533 > 980, we apply the division lemma to 1533 and 980, to get
1533 = 980 x 1 + 553
Step 2: Since the reminder 980 ≠ 0, we apply division lemma to 553 and 980, to get
980 = 553 x 1 + 427
Step 3: We consider the new divisor 553 and the new remainder 427, and apply the division lemma to get
553 = 427 x 1 + 126
We consider the new divisor 427 and the new remainder 126,and apply the division lemma to get
427 = 126 x 3 + 49
We consider the new divisor 126 and the new remainder 49,and apply the division lemma to get
126 = 49 x 2 + 28
We consider the new divisor 49 and the new remainder 28,and apply the division lemma to get
49 = 28 x 1 + 21
We consider the new divisor 28 and the new remainder 21,and apply the division lemma to get
28 = 21 x 1 + 7
We consider the new divisor 21 and the new remainder 7,and apply the division lemma to get
21 = 7 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 980 and 1533 is 7
Notice that 7 = HCF(21,7) = HCF(28,21) = HCF(49,28) = HCF(126,49) = HCF(427,126) = HCF(553,427) = HCF(980,553) = HCF(1533,980) .
