GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 456) = 38760
GCD(680, 456) = ( 680 x 456 ) / 38760
= 680 / 456
= 680
Step2:
LCM(8, 258) = 1032
GCD(8, 258) = ( 8 x 258 ) / 1032
= 8 / 258
= 8
Step3:
LCM(2, 290) = 290
GCD(2, 290) = ( 2 x 290 ) / 290
= 2 / 290
= 2
So, Greatest Common Divisor of 680, 456, 258, 290 is 2
