Given numbers are 102, 771, 786, 784
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 771) = 26214
GCD(102, 771) = ( 102 x 771 ) / 26214
= 102 / 771
= 102
Step2:
LCM(3, 786) = 786
GCD(3, 786) = ( 3 x 786 ) / 786
= 3 / 786
= 3
Step3:
LCM(3, 784) = 2352
GCD(3, 784) = ( 3 x 784 ) / 2352
= 3 / 784
= 3
So, Greatest Common Divisor of 102, 771, 786, 784 is 1
