HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 639, 778, 707 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 639, 778, 707 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 639, 778, 707 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 639, 778, 707 is 1.
HCF(639, 778, 707) = 1
HCF of 639, 778, 707 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 639, 778, 707 is 1.
Highest Common Factor of 639,778,707 is 1
Step 1: Since 778 > 639, we apply the division lemma to 778 and 639, to get
778 = 639 x 1 + 139
Step 2: Since the reminder 639 ≠ 0, we apply division lemma to 139 and 639, to get
639 = 139 x 4 + 83
Step 3: We consider the new divisor 139 and the new remainder 83, and apply the division lemma to get
139 = 83 x 1 + 56
We consider the new divisor 83 and the new remainder 56,and apply the division lemma to get
83 = 56 x 1 + 27
We consider the new divisor 56 and the new remainder 27,and apply the division lemma to get
56 = 27 x 2 + 2
We consider the new divisor 27 and the new remainder 2,and apply the division lemma to get
27 = 2 x 13 + 1
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 639 and 778 is 1
Notice that 1 = HCF(2,1) = HCF(27,2) = HCF(56,27) = HCF(83,56) = HCF(139,83) = HCF(639,139) = HCF(778,639) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 707 > 1, we apply the division lemma to 707 and 1, to get
707 = 1 x 707 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 707 is 1
Notice that 1 = HCF(707,1) .
