Given numbers are 245, 517, 265, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 517) = 126665
GCD(245, 517) = ( 245 x 517 ) / 126665
= 245 / 517
= 245
Step2:
LCM(1, 265) = 265
GCD(1, 265) = ( 1 x 265 ) / 265
= 1 / 265
= 1
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 245, 517, 265, 870 is 1
