GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 286) = 5434
GCD(247, 286) = ( 247 x 286 ) / 5434
= 247 / 286
= 247
Step2:
LCM(13, 318) = 4134
GCD(13, 318) = ( 13 x 318 ) / 4134
= 13 / 318
= 13
Step3:
LCM(1, 648) = 648
GCD(1, 648) = ( 1 x 648 ) / 648
= 1 / 648
= 1
So, Greatest Common Divisor of 247, 286, 318, 648 is 1
