Given numbers are 205, 340, 569, 642
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 340) = 13940
GCD(205, 340) = ( 205 x 340 ) / 13940
= 205 / 340
= 205
Step2:
LCM(5, 569) = 2845
GCD(5, 569) = ( 5 x 569 ) / 2845
= 5 / 569
= 5
Step3:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
So, Greatest Common Divisor of 205, 340, 569, 642 is 1
