Given numbers are 357, 245, 280, 983
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(357, 245) = 12495
GCD(357, 245) = ( 357 x 245 ) / 12495
= 357 / 245
= 357
Step2:
LCM(7, 280) = 280
GCD(7, 280) = ( 7 x 280 ) / 280
= 7 / 280
= 7
Step3:
LCM(7, 983) = 6881
GCD(7, 983) = ( 7 x 983 ) / 6881
= 7 / 983
= 7
So, Greatest Common Divisor of 357, 245, 280, 983 is 1
