Given numbers are 102, 271, 645, 705
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(102, 271) = 27642
GCD(102, 271) = ( 102 x 271 ) / 27642
= 102 / 271
= 102
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 705) = 705
GCD(1, 705) = ( 1 x 705 ) / 705
= 1 / 705
= 1
So, Greatest Common Divisor of 102, 271, 645, 705 is 1
