Given numbers are 402, 786, 436, 979
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 786) = 52662
GCD(402, 786) = ( 402 x 786 ) / 52662
= 402 / 786
= 402
Step2:
LCM(6, 436) = 1308
GCD(6, 436) = ( 6 x 436 ) / 1308
= 6 / 436
= 6
Step3:
LCM(2, 979) = 1958
GCD(2, 979) = ( 2 x 979 ) / 1958
= 2 / 979
= 2
So, Greatest Common Divisor of 402, 786, 436, 979 is 1
