Given numbers are 782, 868, 346, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 868) = 339388
GCD(782, 868) = ( 782 x 868 ) / 339388
= 782 / 868
= 782
Step2:
LCM(2, 346) = 346
GCD(2, 346) = ( 2 x 346 ) / 346
= 2 / 346
= 2
Step3:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
So, Greatest Common Divisor of 782, 868, 346, 643 is 1
