Given numbers are 840, 322, 297, 151
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 322) = 19320
GCD(840, 322) = ( 840 x 322 ) / 19320
= 840 / 322
= 840
Step2:
LCM(14, 297) = 4158
GCD(14, 297) = ( 14 x 297 ) / 4158
= 14 / 297
= 14
Step3:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
So, Greatest Common Divisor of 840, 322, 297, 151 is 1
