HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 840, 528, 291 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 840, 528, 291 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 840, 528, 291 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 840, 528, 291 is 3.
HCF(840, 528, 291) = 3
HCF of 840, 528, 291 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 840, 528, 291 is 3.
Highest Common Factor of 840,528,291 is 3
Step 1: Since 840 > 528, we apply the division lemma to 840 and 528, to get
840 = 528 x 1 + 312
Step 2: Since the reminder 528 ≠ 0, we apply division lemma to 312 and 528, to get
528 = 312 x 1 + 216
Step 3: We consider the new divisor 312 and the new remainder 216, and apply the division lemma to get
312 = 216 x 1 + 96
We consider the new divisor 216 and the new remainder 96,and apply the division lemma to get
216 = 96 x 2 + 24
We consider the new divisor 96 and the new remainder 24,and apply the division lemma to get
96 = 24 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 24, the HCF of 840 and 528 is 24
Notice that 24 = HCF(96,24) = HCF(216,96) = HCF(312,216) = HCF(528,312) = HCF(840,528) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 291 > 24, we apply the division lemma to 291 and 24, to get
291 = 24 x 12 + 3
Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 3 and 24, to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 24 and 291 is 3
Notice that 3 = HCF(24,3) = HCF(291,24) .
