Given numbers are 975, 258, 302, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(975, 258) = 83850
GCD(975, 258) = ( 975 x 258 ) / 83850
= 975 / 258
= 975
Step2:
LCM(3, 302) = 906
GCD(3, 302) = ( 3 x 302 ) / 906
= 3 / 302
= 3
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 975, 258, 302, 638 is 1
