HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 291, 435 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 291, 435 is 3 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 438, 291, 435 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 438, 291, 435 is 3.
HCF(438, 291, 435) = 3
HCF of 438, 291, 435 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 291, 435 is 3.
Highest Common Factor of 438,291,435 is 3
Step 1: Since 438 > 291, we apply the division lemma to 438 and 291, to get
438 = 291 x 1 + 147
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 147 and 291, to get
291 = 147 x 1 + 144
Step 3: We consider the new divisor 147 and the new remainder 144, and apply the division lemma to get
147 = 144 x 1 + 3
We consider the new divisor 144 and the new remainder 3, and apply the division lemma to get
144 = 3 x 48 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 438 and 291 is 3
Notice that 3 = HCF(144,3) = HCF(147,144) = HCF(291,147) = HCF(438,291) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 435 > 3, we apply the division lemma to 435 and 3, to get
435 = 3 x 145 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 435 is 3
Notice that 3 = HCF(435,3) .
