Given numbers are 297, 780, 396, 560
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 780) = 77220
GCD(297, 780) = ( 297 x 780 ) / 77220
= 297 / 780
= 297
Step2:
LCM(3, 396) = 396
GCD(3, 396) = ( 3 x 396 ) / 396
= 3 / 396
= 3
Step3:
LCM(3, 560) = 1680
GCD(3, 560) = ( 3 x 560 ) / 1680
= 3 / 560
= 3
So, Greatest Common Divisor of 297, 780, 396, 560 is 1
