Given numbers are 920, 630, 436, 643
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(920, 630) = 57960
GCD(920, 630) = ( 920 x 630 ) / 57960
= 920 / 630
= 920
Step2:
LCM(10, 436) = 2180
GCD(10, 436) = ( 10 x 436 ) / 2180
= 10 / 436
= 10
Step3:
LCM(2, 643) = 1286
GCD(2, 643) = ( 2 x 643 ) / 1286
= 2 / 643
= 2
So, Greatest Common Divisor of 920, 630, 436, 643 is 1
