Given numbers are 770, 346, 439, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 346) = 133210
GCD(770, 346) = ( 770 x 346 ) / 133210
= 770 / 346
= 770
Step2:
LCM(2, 439) = 878
GCD(2, 439) = ( 2 x 439 ) / 878
= 2 / 439
= 2
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 770, 346, 439, 438 is 1
