HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 842, 598, 143 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 744, 842, 598, 143 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 744, 842, 598, 143 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 744, 842, 598, 143 is 1.
HCF(744, 842, 598, 143) = 1
HCF of 744, 842, 598, 143 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 744, 842, 598, 143 is 1.
Highest Common Factor of 744,842,598,143 is 1
Step 1: Since 842 > 744, we apply the division lemma to 842 and 744, to get
842 = 744 x 1 + 98
Step 2: Since the reminder 744 ≠ 0, we apply division lemma to 98 and 744, to get
744 = 98 x 7 + 58
Step 3: We consider the new divisor 98 and the new remainder 58, and apply the division lemma to get
98 = 58 x 1 + 40
We consider the new divisor 58 and the new remainder 40,and apply the division lemma to get
58 = 40 x 1 + 18
We consider the new divisor 40 and the new remainder 18,and apply the division lemma to get
40 = 18 x 2 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 744 and 842 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(40,18) = HCF(58,40) = HCF(98,58) = HCF(744,98) = HCF(842,744) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 598 > 2, we apply the division lemma to 598 and 2, to get
598 = 2 x 299 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 598 is 2
Notice that 2 = HCF(598,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 143 > 2, we apply the division lemma to 143 and 2, to get
143 = 2 x 71 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 143 is 1
Notice that 1 = HCF(2,1) = HCF(143,2) .
