Given numbers are 297, 658, 840, 880
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 658) = 195426
GCD(297, 658) = ( 297 x 658 ) / 195426
= 297 / 658
= 297
Step2:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
Step3:
LCM(1, 880) = 880
GCD(1, 880) = ( 1 x 880 ) / 880
= 1 / 880
= 1
So, Greatest Common Divisor of 297, 658, 840, 880 is 1
