Given numbers are 442, 945, 245, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(442, 945) = 417690
GCD(442, 945) = ( 442 x 945 ) / 417690
= 442 / 945
= 442
Step2:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
Step3:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
So, Greatest Common Divisor of 442, 945, 245, 516 is 1
