Given numbers are 658, 138, 247, 547
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 138) = 45402
GCD(658, 138) = ( 658 x 138 ) / 45402
= 658 / 138
= 658
Step2:
LCM(2, 247) = 494
GCD(2, 247) = ( 2 x 247 ) / 494
= 2 / 247
= 2
Step3:
LCM(1, 547) = 547
GCD(1, 547) = ( 1 x 547 ) / 547
= 1 / 547
= 1
So, Greatest Common Divisor of 658, 138, 247, 547 is 1
