Given numbers are 498, 977, 245, 830
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(498, 977) = 486546
GCD(498, 977) = ( 498 x 977 ) / 486546
= 498 / 977
= 498
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 830) = 830
GCD(1, 830) = ( 1 x 830 ) / 830
= 1 / 830
= 1
So, Greatest Common Divisor of 498, 977, 245, 830 is 1
