Given numbers are 149, 258, 684, 515
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(149, 258) = 38442
GCD(149, 258) = ( 149 x 258 ) / 38442
= 149 / 258
= 149
Step2:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
Step3:
LCM(1, 515) = 515
GCD(1, 515) = ( 1 x 515 ) / 515
= 1 / 515
= 1
So, Greatest Common Divisor of 149, 258, 684, 515 is 1
