Given numbers are 213, 551, 531, 684
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 551) = 117363
GCD(213, 551) = ( 213 x 551 ) / 117363
= 213 / 551
= 213
Step2:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
Step3:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
So, Greatest Common Divisor of 213, 551, 531, 684 is 1
