Steps to Calculate GCD of 805, 529, 857, 649 using LCM Formula
Given numbers are 805, 529, 857, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 529) = 18515
GCD(805, 529) = ( 805 x 529 ) / 18515
= 805 / 529
= 805
Step2:
LCM(23, 857) = 19711
GCD(23, 857) = ( 23 x 857 ) / 19711
= 23 / 857
= 23
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 805, 529, 857, 649 is 1
