Given numbers are 217, 763, 330, 557
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 763) = 23653
GCD(217, 763) = ( 217 x 763 ) / 23653
= 217 / 763
= 217
Step2:
LCM(7, 330) = 2310
GCD(7, 330) = ( 7 x 330 ) / 2310
= 7 / 330
= 7
Step3:
LCM(1, 557) = 557
GCD(1, 557) = ( 1 x 557 ) / 557
= 1 / 557
= 1
So, Greatest Common Divisor of 217, 763, 330, 557 is 1
