HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 742, 240, 889 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 742, 240, 889 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, 240, 889 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, 240, 889 is 1.
HCF(742, 240, 889) = 1
HCF of 742, 240, 889 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, 240, 889 is 1.
Highest Common Factor of 742,240,889 is 1
Step 1: Since 742 > 240, we apply the division lemma to 742 and 240, to get
742 = 240 x 3 + 22
Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 22 and 240, to get
240 = 22 x 10 + 20
Step 3: We consider the new divisor 22 and the new remainder 20, and apply the division lemma to get
22 = 20 x 1 + 2
We consider the new divisor 20 and the new remainder 2, and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 742 and 240 is 2
Notice that 2 = HCF(20,2) = HCF(22,20) = HCF(240,22) = HCF(742,240) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 889 > 2, we apply the division lemma to 889 and 2, to get
889 = 2 x 444 + 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 889 is 1
Notice that 1 = HCF(2,1) = HCF(889,2) .
