HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 939, 501, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 939, 501, 668 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 939, 501, 668 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 939, 501, 668 is 1.
HCF(939, 501, 668) = 1
HCF of 939, 501, 668 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 939, 501, 668 is 1.
Highest Common Factor of 939,501,668 is 1
Step 1: Since 939 > 501, we apply the division lemma to 939 and 501, to get
939 = 501 x 1 + 438
Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 438 and 501, to get
501 = 438 x 1 + 63
Step 3: We consider the new divisor 438 and the new remainder 63, and apply the division lemma to get
438 = 63 x 6 + 60
We consider the new divisor 63 and the new remainder 60,and apply the division lemma to get
63 = 60 x 1 + 3
We consider the new divisor 60 and the new remainder 3,and apply the division lemma to get
60 = 3 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 939 and 501 is 3
Notice that 3 = HCF(60,3) = HCF(63,60) = HCF(438,63) = HCF(501,438) = HCF(939,501) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 668 > 3, we apply the division lemma to 668 and 3, to get
668 = 3 x 222 + 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 668 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(668,3) .
