Given numbers are 258, 280, 660, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 280) = 36120
GCD(258, 280) = ( 258 x 280 ) / 36120
= 258 / 280
= 258
Step2:
LCM(2, 660) = 660
GCD(2, 660) = ( 2 x 660 ) / 660
= 2 / 660
= 2
Step3:
LCM(2, 356) = 356
GCD(2, 356) = ( 2 x 356 ) / 356
= 2 / 356
= 2
So, Greatest Common Divisor of 258, 280, 660, 356 is 2
