Given numbers are 987, 938, 970, 297
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 938) = 132258
GCD(987, 938) = ( 987 x 938 ) / 132258
= 987 / 938
= 987
Step2:
LCM(7, 970) = 6790
GCD(7, 970) = ( 7 x 970 ) / 6790
= 7 / 970
= 7
Step3:
LCM(1, 297) = 297
GCD(1, 297) = ( 1 x 297 ) / 297
= 1 / 297
= 1
So, Greatest Common Divisor of 987, 938, 970, 297 is 1
