Given numbers are 217, 236, 418, 780
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(217, 236) = 51212
GCD(217, 236) = ( 217 x 236 ) / 51212
= 217 / 236
= 217
Step2:
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
= 1 / 418
= 1
Step3:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
So, Greatest Common Divisor of 217, 236, 418, 780 is 1
