HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 309, 742, 877, 542 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 309, 742, 877, 542 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 309, 742, 877, 542 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 309, 742, 877, 542 is 1.
HCF(309, 742, 877, 542) = 1
HCF of 309, 742, 877, 542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 309, 742, 877, 542 is 1.
Highest Common Factor of 309,742,877,542 is 1
Step 1: Since 742 > 309, we apply the division lemma to 742 and 309, to get
742 = 309 x 2 + 124
Step 2: Since the reminder 309 ≠ 0, we apply division lemma to 124 and 309, to get
309 = 124 x 2 + 61
Step 3: We consider the new divisor 124 and the new remainder 61, and apply the division lemma to get
124 = 61 x 2 + 2
We consider the new divisor 61 and the new remainder 2,and apply the division lemma to get
61 = 2 x 30 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 309 and 742 is 1
Notice that 1 = HCF(2,1) = HCF(61,2) = HCF(124,61) = HCF(309,124) = HCF(742,309) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 877 > 1, we apply the division lemma to 877 and 1, to get
877 = 1 x 877 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 877 is 1
Notice that 1 = HCF(877,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 1, we apply the division lemma to 542 and 1, to get
542 = 1 x 542 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 542 is 1
Notice that 1 = HCF(542,1) .
