HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 746, 840 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 746, 840 is 2 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 440, 746, 840 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 440, 746, 840 is 2.
HCF(440, 746, 840) = 2
HCF of 440, 746, 840 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 746, 840 is 2.
Highest Common Factor of 440,746,840 is 2
Step 1: Since 746 > 440, we apply the division lemma to 746 and 440, to get
746 = 440 x 1 + 306
Step 2: Since the reminder 440 ≠ 0, we apply division lemma to 306 and 440, to get
440 = 306 x 1 + 134
Step 3: We consider the new divisor 306 and the new remainder 134, and apply the division lemma to get
306 = 134 x 2 + 38
We consider the new divisor 134 and the new remainder 38,and apply the division lemma to get
134 = 38 x 3 + 20
We consider the new divisor 38 and the new remainder 20,and apply the division lemma to get
38 = 20 x 1 + 18
We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get
20 = 18 x 1 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 440 and 746 is 2
Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(38,20) = HCF(134,38) = HCF(306,134) = HCF(440,306) = HCF(746,440) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 840 > 2, we apply the division lemma to 840 and 2, to get
840 = 2 x 420 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 840 is 2
Notice that 2 = HCF(840,2) .
