HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 402, 135, 477, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 402, 135, 477, 802 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 402, 135, 477, 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 402, 135, 477, 802 is 1.
HCF(402, 135, 477, 802) = 1
HCF of 402, 135, 477, 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 402, 135, 477, 802 is 1.
Highest Common Factor of 402,135,477,802 is 1
Step 1: Since 402 > 135, we apply the division lemma to 402 and 135, to get
402 = 135 x 2 + 132
Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 132 and 135, to get
135 = 132 x 1 + 3
Step 3: We consider the new divisor 132 and the new remainder 3, and apply the division lemma to get
132 = 3 x 44 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 402 and 135 is 3
Notice that 3 = HCF(132,3) = HCF(135,132) = HCF(402,135) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 477 > 3, we apply the division lemma to 477 and 3, to get
477 = 3 x 159 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 477 is 3
Notice that 3 = HCF(477,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 3, we apply the division lemma to 802 and 3, to get
802 = 3 x 267 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 802 is 1
Notice that 1 = HCF(3,1) = HCF(802,3) .
