Given numbers are 206, 646, 821, 519
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 646) = 66538
GCD(206, 646) = ( 206 x 646 ) / 66538
= 206 / 646
= 206
Step2:
LCM(2, 821) = 1642
GCD(2, 821) = ( 2 x 821 ) / 1642
= 2 / 821
= 2
Step3:
LCM(1, 519) = 519
GCD(1, 519) = ( 1 x 519 ) / 519
= 1 / 519
= 1
So, Greatest Common Divisor of 206, 646, 821, 519 is 1
