Given numbers are 316, 790, 945, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(316, 790) = 1580
GCD(316, 790) = ( 316 x 790 ) / 1580
= 316 / 790
= 316
Step2:
LCM(158, 945) = 149310
GCD(158, 945) = ( 158 x 945 ) / 149310
= 158 / 945
= 158
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 316, 790, 945, 245 is 1
