HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 666, 542 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 938, 666, 542 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 938, 666, 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 938, 666, 542 is 2.
HCF(938, 666, 542) = 2
HCF of 938, 666, 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 938, 666, 542 is 2.
Highest Common Factor of 938,666,542 is 2
Step 1: Since 938 > 666, we apply the division lemma to 938 and 666, to get
938 = 666 x 1 + 272
Step 2: Since the reminder 666 ≠ 0, we apply division lemma to 272 and 666, to get
666 = 272 x 2 + 122
Step 3: We consider the new divisor 272 and the new remainder 122, and apply the division lemma to get
272 = 122 x 2 + 28
We consider the new divisor 122 and the new remainder 28,and apply the division lemma to get
122 = 28 x 4 + 10
We consider the new divisor 28 and the new remainder 10,and apply the division lemma to get
28 = 10 x 2 + 8
We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get
10 = 8 x 1 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 938 and 666 is 2
Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(28,10) = HCF(122,28) = HCF(272,122) = HCF(666,272) = HCF(938,666) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 542 > 2, we apply the division lemma to 542 and 2, to get
542 = 2 x 271 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 542 is 2
Notice that 2 = HCF(542,2) .
