Given numbers are 709, 263, 646, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(709, 263) = 186467
GCD(709, 263) = ( 709 x 263 ) / 186467
= 709 / 263
= 709
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 655) = 655
GCD(1, 655) = ( 1 x 655 ) / 655
= 1 / 655
= 1
So, Greatest Common Divisor of 709, 263, 646, 655 is 1
