Given numbers are 297, 870, 626, 855
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 870) = 86130
GCD(297, 870) = ( 297 x 870 ) / 86130
= 297 / 870
= 297
Step2:
LCM(3, 626) = 1878
GCD(3, 626) = ( 3 x 626 ) / 1878
= 3 / 626
= 3
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 297, 870, 626, 855 is 1
