Given numbers are 858, 490, 767, 392
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 490) = 210210
GCD(858, 490) = ( 858 x 490 ) / 210210
= 858 / 490
= 858
Step2:
LCM(2, 767) = 1534
GCD(2, 767) = ( 2 x 767 ) / 1534
= 2 / 767
= 2
Step3:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
So, Greatest Common Divisor of 858, 490, 767, 392 is 1
