HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 888, 771, 542 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 888, 771, 542 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 888, 771, 542 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 888, 771, 542 is 1.
HCF(888, 771, 542) = 1
HCF of 888, 771, 542 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 888, 771, 542 is 1.
Highest Common Factor of 888,771,542 is 1
Step 1: Since 888 > 771, we apply the division lemma to 888 and 771, to get
888 = 771 x 1 + 117
Step 2: Since the reminder 771 ≠ 0, we apply division lemma to 117 and 771, to get
771 = 117 x 6 + 69
Step 3: We consider the new divisor 117 and the new remainder 69, and apply the division lemma to get
117 = 69 x 1 + 48
We consider the new divisor 69 and the new remainder 48,and apply the division lemma to get
69 = 48 x 1 + 21
We consider the new divisor 48 and the new remainder 21,and apply the division lemma to get
48 = 21 x 2 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 888 and 771 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(48,21) = HCF(69,48) = HCF(117,69) = HCF(771,117) = HCF(888,771) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 3, we apply the division lemma to 542 and 3, to get
542 = 3 x 180 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 542 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(542,3) .
