HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 502, 542, 440, 802 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 502, 542, 440, 802 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 502, 542, 440, 802 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 502, 542, 440, 802 is 2.
HCF(502, 542, 440, 802) = 2
HCF of 502, 542, 440, 802 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 502, 542, 440, 802 is 2.
Highest Common Factor of 502,542,440,802 is 2
Step 1: Since 542 > 502, we apply the division lemma to 542 and 502, to get
542 = 502 x 1 + 40
Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 40 and 502, to get
502 = 40 x 12 + 22
Step 3: We consider the new divisor 40 and the new remainder 22, and apply the division lemma to get
40 = 22 x 1 + 18
We consider the new divisor 22 and the new remainder 18,and apply the division lemma to get
22 = 18 x 1 + 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 502 and 542 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(22,18) = HCF(40,22) = HCF(502,40) = HCF(542,502) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 440 > 2, we apply the division lemma to 440 and 2, to get
440 = 2 x 220 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 440 is 2
Notice that 2 = HCF(440,2) .
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) .
