Given numbers are 494, 646, 516, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(494, 646) = 8398
GCD(494, 646) = ( 494 x 646 ) / 8398
= 494 / 646
= 494
Step2:
LCM(38, 516) = 9804
GCD(38, 516) = ( 38 x 516 ) / 9804
= 38 / 516
= 38
Step3:
LCM(2, 253) = 506
GCD(2, 253) = ( 2 x 253 ) / 506
= 2 / 253
= 2
So, Greatest Common Divisor of 494, 646, 516, 253 is 1
