Given numbers are 780, 438, 857, 294
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 438) = 56940
GCD(780, 438) = ( 780 x 438 ) / 56940
= 780 / 438
= 780
Step2:
LCM(6, 857) = 5142
GCD(6, 857) = ( 6 x 857 ) / 5142
= 6 / 857
= 6
Step3:
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
= 1 / 294
= 1
So, Greatest Common Divisor of 780, 438, 857, 294 is 1
