HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 1553 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 1553 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 742, 1553 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 742, 1553 is 1.
HCF(742, 1553) = 1
HCF of 742, 1553 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 742, 1553 is 1.
Highest Common Factor of 742,1553 is 1
Step 1: Since 1553 > 742, we apply the division lemma to 1553 and 742, to get
1553 = 742 x 2 + 69
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 69 and 742, to get
742 = 69 x 10 + 52
Step 3: We consider the new divisor 69 and the new remainder 52, and apply the division lemma to get
69 = 52 x 1 + 17
We consider the new divisor 52 and the new remainder 17,and apply the division lemma to get
52 = 17 x 3 + 1
We consider the new divisor 17 and the new remainder 1,and apply the division lemma to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 742 and 1553 is 1
Notice that 1 = HCF(17,1) = HCF(52,17) = HCF(69,52) = HCF(742,69) = HCF(1553,742) .
