HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 553, 942 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 553, 942 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 553, 942 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 553, 942 is 1.
HCF(553, 942) = 1
HCF of 553, 942 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 553, 942 is 1.
Highest Common Factor of 553,942 is 1
Step 1: Since 942 > 553, we apply the division lemma to 942 and 553, to get
942 = 553 x 1 + 389
Step 2: Since the reminder 553 ≠ 0, we apply division lemma to 389 and 553, to get
553 = 389 x 1 + 164
Step 3: We consider the new divisor 389 and the new remainder 164, and apply the division lemma to get
389 = 164 x 2 + 61
We consider the new divisor 164 and the new remainder 61,and apply the division lemma to get
164 = 61 x 2 + 42
We consider the new divisor 61 and the new remainder 42,and apply the division lemma to get
61 = 42 x 1 + 19
We consider the new divisor 42 and the new remainder 19,and apply the division lemma to get
42 = 19 x 2 + 4
We consider the new divisor 19 and the new remainder 4,and apply the division lemma to get
19 = 4 x 4 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 553 and 942 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(19,4) = HCF(42,19) = HCF(61,42) = HCF(164,61) = HCF(389,164) = HCF(553,389) = HCF(942,553) .
