Given numbers are 218, 781, 280, 265
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(218, 781) = 170258
GCD(218, 781) = ( 218 x 781 ) / 170258
= 218 / 781
= 218
Step2:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
Step3:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
So, Greatest Common Divisor of 218, 781, 280, 265 is 1
