HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 398, 940, 802, 676 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 398, 940, 802, 676 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 398, 940, 802, 676 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 398, 940, 802, 676 is 2.
HCF(398, 940, 802, 676) = 2
HCF of 398, 940, 802, 676 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 398, 940, 802, 676 is 2.
Highest Common Factor of 398,940,802,676 is 2
Step 1: Since 940 > 398, we apply the division lemma to 940 and 398, to get
940 = 398 x 2 + 144
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 144 and 398, to get
398 = 144 x 2 + 110
Step 3: We consider the new divisor 144 and the new remainder 110, and apply the division lemma to get
144 = 110 x 1 + 34
We consider the new divisor 110 and the new remainder 34,and apply the division lemma to get
110 = 34 x 3 + 8
We consider the new divisor 34 and the new remainder 8,and apply the division lemma to get
34 = 8 x 4 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 398 and 940 is 2
Notice that 2 = HCF(8,2) = HCF(34,8) = HCF(110,34) = HCF(144,110) = HCF(398,144) = HCF(940,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 2, we apply the division lemma to 802 and 2, to get
802 = 2 x 401 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 802 is 2
Notice that 2 = HCF(802,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 676 > 2, we apply the division lemma to 676 and 2, to get
676 = 2 x 338 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 676 is 2
Notice that 2 = HCF(676,2) .
